In each iteration , part of the constraints of the EE optimization problem are removed by exploiting the penalty function approach . We further propose a novel two-layer approach , which allows finding the optimum at each iteration by decoupling the EE optimization problem of joint resource allocation and power control into two separate steps .

Abstract Recently an opportunistic incremental relaying ( OIR ) system has been studied for improving the performance degradation in fading channel . However there are few studies on power control in the system , and the studies are assumed perfect knowledge of the all channels at transmitters . The assumption that the source know all channel information is difficult in practical channels . In the construction of nuclear power plants , craning operation is very important . In the structures of cranes , the most important and technological representative is the hoisting structure , which is highest in power controlling , widest in the scope of speed con-trolling and the most difficult to maintain , and its performance should be improved with the application of frequency technology . A 402-output TFT-LCD driver with a power-controlling function by selecting a number of colors to be displayed is described . Power-controlling is realized by turning on and off reference voltage buffers used in DACs to convert RGB digital signals . The buffers must drive 1 to 402 capacitive loads . However , this methodology requires a characterization of the feasible SIR region . We derive a log-convexity property of the feasible SIR region , which is potentially useful for the design of a power-controlled system . Hybrid slow frequency hopping (SFH)/SC-CDMA : Overlapped carrier allocation ( OCA ) schemes can be applied to hybrid SFH/SC-CDMA . In power controlled systems , SFH/SC-CDMA is known to be much worse than pure DS-CDMA in terms of capacity . Introduction of OCA to SFH/SC-CDMA improves capacity significantly , and consequently it becomes comparable to pure DS-CDMA whilst merits of frequency hopping such as strong immunity to near/far effect is preserved . We present a study of average efficiency of power amplifiers ( PAs ) in power-controlled systems with multi-antenna diversity . The efficiencies are analytically calculated using the transmitted power distributions . Error detecting unit generates a response signal corresponding to whether the error was detected in the packet data received through the wireless channel , diffuser , and outputs the spreading of the response signal . Transmission power controller is to perform a power control operation for a response signal spread by the different power values ​​in accordance with the packet data transmission rate of a packet data channel , the transmission unit is a radio channel the response signal output by the transmission power controller through to send . Then , virtual operation data under compressor fouling were generated and used for the validation of the logic . The conventional diagnostic logic could predict the degradation in usual operation but could not evaluate the actual performance degradation correctly in a power control operation where power generation should comply with the power demand . However , the new logic evaluated the exact performance degradation for the entire period analyzed . However , little work has been done to explore the use of spreadsheet techniques in power system operation . In this paper the common spreadsheet concept used for answering the " what if " question is extended to conveniently answer the questions of " what was " or " what will be " in power control operation . Enhanced with features needed to support automated data collection and processing in a real-time electric utility control , the extended spreadsheet concept has been implemented in a delivered power control computer . The prediction of signal power in code division multiple access ( CDMA ) systems in urban radio channels is investigated . We focus on the processing of the measured input signal for power control purposes in a mobile station receiver . Predictive filtering based on a polynomial signal model is proposed , and a class of FIR-type polynomial filters is investigated with simulations . Employing optical frequency multiplication , we demonstrate experimentally the simultaneous delivery of different 64QAM radio signals at 5.8 and 17.7 GHz after 4.4 km of multimode fiber in a single radio-over-fiber link . We also propose a flexible mechanism for the dynamic radio link adaptation , and the simultaneous transmission of an in-band control channel with the wireless data channels for power control purposes at the antenna site is demonstrated experimentally Apparatus and methods for power control management in a user equipment ( UE ) include establishing a first call and a second call at the UE , wherein the first call is associated with a first subscription and the second call is associated with a second subscription . Further , the apparatus and methods include determining concurrency of the first call and the second call . We have developed a closed form mathematical expressions analytically for this protocol . We have also studied the power control aspects in this environment and we derived a closed form mathematical expressions analytically for this power control technique . This hybrid protocol is capable of integrating different types of traffic ( like CBR , VBR and ABR services ) and compiles with the requirements of next-generation systems . Many safety-related applications in Vehicular Ad Hoc Networks require fast and reliable emergency message dissemination through multi-hop broadcast . However , the conventional broadcast mechanism is neither efficient nor reliable because it results in serious contention and collisions , which is usually referred to as the broadcast storm problem . The recent developments in industry of vehicles and technology based on wireless communication , has led to tremendous progress in vehicular ad-hoc networks . Using the Wireless Sensor Networks ( WSNs ) , the user can get a lot of traffic information like traffic congestion , average speed of vehicles on road , accidents if any occurred , etc . The proliferation of billions of connected devices along with their ever growing data demands can potentially cause severe congestion in vehicular networks unless effective solutions are developed . In this context , the multiuser interference encountered in vehicular ad hoc networks is a major performance bottleneck . The interference among vehicles needs to be harnessed to meet the high data rate requirements of heterogeneous vehicular communication networks . Furthermore , for above derived statistical properties , we give an detailed analysis about them by comparing their closeness between simulation and theoretical results at the different speed ratios of transmitted and received nodes . In addition , we also describe the curves of level crossing rate ( LCR ) and average fade duration ( AFD ) at various speed ratios , it is manifested that the larger speed ratio contributes to larger fading depth and faster fluctuation of received signal , which provides a reference for the protocol design in Vehicle Ad Hoc Network ( VANET ) . Vehicle ad hoc network is the key technology for a future Internet of vehicles and intelligent transport system . However , involvement of vast number of vehicles in Internet of vehicles limits the performance of vehicle ad hoc network . With the ever grower demand for spectrum , there exists an urgent need to improve spectrum utilization in wireless networks . Cognitive radio technology , which serves as a means to improve spectrum utilization , is expected to become an important part of diverse fields including the field of vehicular ad-hoc networking . The CRAVENET paradigm introduces entirely new challenges and security threats . Vehicle connectivity can be considered as an emerging technology that provides dissemination of warning messages and traffic information to vehicles running on the road . The deployment of vehicular ad-hoc network communication is strictly dependent on strictly on their security and privacy features . Recent advances in the hardware and software technology , tremendous improvements are made . For the characteristics of high speed mobility of nodes , frequent changes of dynamic topology and frequent interrupts of the communication links in the VANET , this paper analyzed the defect of the current mobile ad-hoc network routing protocol , and carried on the simulation analysis on the adaptability of AODV , DSR and DSDV routing protocols in VANET applications in the VANET . Through the above research , this paper obtained the conclusion that the AODV routing protocol is more suitable for vehicular ad hoc network environment In this paper , we design an access control mechanism for vehicular ad hoc network environment to enable only authorized vehicles to access data using attribute based encryption . The existing access control schemes are expensive in the sense that the ciphertext-length grows linearly with the number of attributes occurring in the access policy and the number of pairings needed for decryption is linear to the minimum number of attributes satisfying the access policy to decrypt a message . Based on the characteristic of vehicle mobile ad hoc network , for the first time , this paper analyzes the unstable situations of routing in vehicular mobile ad hoc network from the point of routing fracture , then proposes a GPS-free routing protocol RSBA(Relative Stability Based AODV Routing Protocol),with vehicle 's relative stability as it 's auxiliary parameter in routing establish process . Simulation shows RSBA 's lower route broken rate and routing overhead , as well as it 's better performances in reducing packet drop rate compared with AODV in high node 's density urban vehicle environment and validates the correctness of the analytic strategy and conclusions of the stability of vehicle mobile ad hoc network . This scheme uses velocity property as intertier 's handoff rule while uses the pilot signal strength as intratier 's handoff rule . From the simulation results , the conclusion is given that the new scheme not only ensures low handoff failure probability for high-speed mobile services but also enhances the capacity of hierarchical system , and optimizes the handoff performance for all kinds of services The widespread introduction of white LEDs has brought an unprecedented opportunity to create a ubiquitous indoor visible light communication system . In order to satisfy the illumination requirements , signals from multiple LEDs are always superposed on the receiving surface which causes severe inter-cell interference and leads to a critical demand for cell identification for scheduling and handoff . In this paper , we propose a visible light cell identification ( VLCID ) scheme based on cumulative space time coding ( CSTC ) to solve this problem . However , to improve the scalability of our architecture , we have designed an efficient distributed Middleware Service layer that properly maintains application session handoff semantics while being able to service a large number of clients . We show that this service layer improves the scalability of general client-to-application server interaction as well as the specific case of application session handoff . We detail protocols involved in performing handoff and analyse an implementation of the architecture that supports the use of a real medical teaching tool . Middleware layers placed between user clients and applicationservers have been used to perform a variety of functions . Inprevious work we have used middleware to perform a new capability , application session handoff , using a single Middleware Server toprovide all functionality . However , to improve the scalability ofour architecture , we have designed an efficient distributedMiddleware Service layer that properly maintains applicationsession handoff semantics while being able to service a largenumber of clients . In this paper , we focus on the handoff scenario in which there is a need to relocate ( or provision ) certain application-specific functionality to ensure the seamless continuation of the user 's application after handoff . We provide a solution framework called the application context transfer ( ACT ) framework to address this need and describe its application to such handoff scenarios . TCP being an end-to-end protocol has performance problems as its behaviour depends on the end-to-end path characteristics which are likely to be affected by a vertical handoff . We carry out a systematic study of TCP behaviour and the consequent problems that arise in various handoff scenarios between networks with different bandwidth and delay characteristics . This study can serve as a basis to evaluate any modifications to the TCP algorithm to adapt to a vertical handoff . The mobility support of mobile terminals in a mixed IPv4/IPv6 environment remains largely unexplored . In this paper , we analyze various handoff scenarios for a dual stack mobile node with a predominant IPv6 home address ( DSMNv6 ) roaming in a mixed IPv4/IPv6 environment . We investigate how handoffs can be supported and derive the handoff procedures for all scenarios . This paper studies the buffer control issues that are related to supporting a seamless stream handoff in a WLAN environment that employs simulcast streaming . We analyze the impacts of the handoff disruption period and inter-AR synchronization variance . We also derive theoretical results that concern how a seamless stream handoff can be guaranteed in terms of the minimum buffer and backlog requirements . Based on the results , an MH-controlled-AR-pushed buffer control scheme is proposed and its cooperation with FMIPv6 is also discussed . One of the prominent issues these days is the support for heterogeneous handoff . Different types of network come with high end data rates for rapid data transmission . Due to the popularity of the IEEE 802.11-based LANs and fast development of the IEEE 802.16e MANs , we can expect a heterogeneous network consisting of 802.11-based and 802.16e networks in the near future . In such an environment , heterogeneous handoff is possible . How to keep guaranteeing the handoff connection its QoS demand , and in the meantime , avoid impacting on other connections is a challenge to support real-time applications in a heterogeneous network . In this paper , we introduce a subclass of fractional channel policy , called uniform fractional channel policy ( UFC ) and study its performance . Expressions for both dropping probability of handoff calls and blocking probability of new calls are derived . Then it is shown that there is an optimal value for the parameter of UFC , which minimizes the blocking probability of new calls with the constraint on the upper bound on the dropping probability of handoff calls . The theme of this thesis is the advancement of IP mobility management mechanisms to support robustly the delay requirements of interactive IP applications services . Current IPv6 mobility management standards are heavily dependent on reactive manipulations of the IP handoff process . Such modus operandi appears to be insufficient to address delay transparency during interactive IP communications . On the other hand , the emerged concept of edge mobile computing has gained crucial attention by researchers that could help in reducing computational complexities and decreasing communication delay . Hence , this paper specifically studies the handoff challenges in cluster based handoff using new concept of dynamic edge-backup node . The outcomes are evaluated and contrasted with the network mobility method , our proposed technique , and other cluster-based technologies . The location information of sensor nodes is utilized to achieve the IPv6-address configuration algorithm and the routing algorithm . In the mobility handoff algorithm , neither does a mobile sensor node need a care-of address during the mobility process , nor is involved in the mobility handoff process . Therefore , a mobile sensor node 's power consumption is reduced and the life span is prolonged . A plurality of orthogonal data streams input variable spreading factor ( OVSF ) code and a spreader for spreading using one of , the spread of the data string to the primary scrambling used by default code or a plurality of the secondary in accordance with the terminal number of in communication in the scrambling code generator for generating a scrambling code different from a scrambling code for the use of compressed mode in a base station apparatus having a scrambler for scrambling one of the scrambling codes , with a predetermined bit in the initial first for generating the m sequences with a linear feedback shift register and a predetermined bit initially the m-sequence by the other m a second linear feedback shift register and said first and second adding the outputs of the linear feedback shift register , and in use the scrambling code to generate the sequence the first is to generate Group , the second and a second adder for adding the output from the first one-bit-delayed outputs the output of the linear feedback shift register of the linear feedback shift register , the second output and said first linear feedback shift of the linear feedback shift register the third adder by the other scrambling code having the adding the 2-bit-delayed output of the register output to the second and third adders to either one of the output and said scrambler is a scrambling code different from the to the spread data sequence of the characterized in that the scrambling . Multiple scrambling , inter-frequency handoff , the compressed mode transmission We propose to utilize the filtered Gaussian phase dither technique for the effective suppression of the multipath- interference ( MPI ) noises caused by multiple bad fiber connectors in the mobile fronthaul network ( MFN ) based on the radio-over- fiber ( RoF ) technology . We first evaluate the viable performances of the RoF-based MFN in the 5 G wireless communication systems by using this technique and deduce the required bandwidth and phase modulation depth of the filtered Gaussian dither signal for the suppression of the MPI noises by numerical simulations . The results show that , by using the proposed technique , it is possible to suppress the MPI noises by ∼10 dB regardless of the number of bad fiber connectors . In 5 G wireless networks , the perspective of very large number of simultaneous connections is challenging . In this sense , an overloaded system is a basic scenario of 5 G multiple access techniques , that is , the number of active users is greater than the number of system subcarriers . In our proposed infrastructure the widespread used passive optical access network ( PON ) architecture is technologically transformed to the AROF-WDM-PON transmission system without replacing existing network elements , by integrating baseband units ( BBUs ) or mobile radio transmitters located in optical line terminal ( OLT ) at the central office ( CO ) and the receiving radio unit ( RU ) part of mobile base stations , leaving the traditional WDM-PON broadband architecture unchanged . In our investigated ARoF-WDM PON transmission system model , designed in the simulation environment , we research the possible ARoF system implementation scenarios into the PON ’s segment , which has been now standardized to the 40 Gigabit-capable next-generation passive optical network ( NG-PON2 ) standard providing an unique solution for hybrid fiber optical infrastructure serving as the next step for future 5 G wireless communication networks . For 5 G wireless communication networks , low latency and high spectral efficiency are required to provide ubiquitous communication for emerging applications . In this letter , we propose a novel framework which considers these requirements simultaneously by integrating the notion of effective capacity ( EC ) and non-orthogonal multiple access ( NOMA ) into virtualized wireless networks ( VWNs ) . The Co-frequency Co-time Full Duplex ( CCFD ) is a key concept in 5 G wireless communication networks . The biggest challenge for CCFD wireless communication is the strong self-interference ( SI ) from near-end transceivers . Polar codes achieve outstanding error correction performance when using successive cancellation list ( SCL ) decoding with cyclic redundancy check . A larger list size brings better decoding performance and is essential for practical applications such as 5 G communication networks . However , the decoding speed of SCL decreases with increased list size . Abstract Heterogeneous cloud radio access network ( H-CRAN ) is a promising technology to help overcome the traffic density which in 5 G communication networks . One of the main challenges that will arise in H-CRAN is how to minimize energy consumption . Corresponding to full-duplex transmission at the PHY layer , we also develop and analyze the fullduplex MAC protocol at the MAC layer to implement full-duplex transmission over the entire 5 G mobile wireless network architecture . Through simulation experiments we show that our proposed schemes can significantly enhance spectrum efficiency for 5 G mobile wireless networks . In the all-IP wireless networks , mobility management is a crucial issue , and it can be operated at different layers in the traditional Transmission Control Protocol/Internet Protocol ( TCP/IP ) stack . Session Initiation Protocol ( SIP ) is an application layer protocol used for the signaling and the mobility management without any modifications of the lower layer protocols , especially in the voice over IP environment . Next-generation wireless systems are envisioned to have all Internet Protocol ( IP ) based infrastructure with the support of heterogeneous access technologies . One of the research challenges for next generation all-IP-based wireless systems is the design of intelligent mobility management techniques that take advantage of IP-based technologies to achieve global roaming among various access technologies . In this paper a new wireless network architecture for mobility management is proposed to integrate the cellular system and Wireless Local Area Network ( WLAN ) of various providers that may not necessarily have direct service level agreement ( SLA ) among them . Service management addresses the issues of how to efficiently deliver services to mobile nodes . This dissertation aims to design and analyze integrated mobility and service management schemes for future all-IP based wireless systems . We propose and analyze peruser regional registration schemes for integrated mobility and service management with the goal to minimize the network signaling and packet delivery cost in future all-IP based wireless networks . According to the performed analysis , this paper presents VoIP Quality ( in terms of R-factor ) during handoff scenarios for various VoIP codecs using the aforementioned mobility protocol through OPNET simulation . Through simulation , it is shown that the achieved reduction of Handoff Delay can lead to VoIP Quality improvements in terms of service continuity in all-IP Wireless Access Networking environments . Mobility management is an important task in wireless networks . The Mobile IP protocol provides a basic solution to mobility management in future all-IP wireless network environments . However , Mobile IP suffers from several problems such as triangular routing , long distant and frequent registration update . Multiple configurations of side-channel and fault protection enable the programmer to select the desired number of shares and the desired redundancy level for each slice . Recurring and security-sensitive operations are supported in hardware through a custom instruction set extension . The new instructions support bitslicing , secret-share generation , redundant logic computation , and fault detection .

Cryptographic Data Security . Block ciphers . " The present paper is devoted to creation of cryptographic data security and realization of the packet mode in the distributed information measurement and control system that implements methods of optical spectroscopy for plasma physics research and atomic collisions . This system gives a remote access to information and instrument resources within the Intranet/Internet networks . This is a promising computing model especially in the context of Big Data . However , renting computing capabilities from a cloud provider means the integration of external resources into the own infrastructure and this requires a great amount of trust and raises new data security and privacy challenges . With respect to these still unsolved problems , this work presents a fixed vertical partitioning and distribution approach that uses traditional relational data models and distributes the corresponding partitions vertically across different cloud providers . However for data to be used to their full power , data security and privacy are critical . Even though data security and privacy have been widely investigated over the past thirty years , today we face new difficult data security and privacy challenges . Some of those challenges arise from increasing privacy concerns with respect to the use of data and from the need of reconciling privacy with the use of data for security in applications such as homeland protection , counterterrorism , and health , food and water security . Network security situation awareness ( NSSA ) is a hotspot in the network security research field , based on the security situation values , decision makers can be aware of the actual security situation of their networks and then make rational decision to make their networks safer . In this paper , we build a multi-level quantization model for NSSA firstly ; this model is comprised of three levels , namely , special oriented level , essential oriented level and holistic level . An automatic speaker verification system is investigated as a means of reinforcing speech recognition security . The system 's implementation is independent of speaker population size . System security administration has , for the most part , been largely ignored as network administration has flourished . The result of this is that there are large installations of NT that need to be retrofitted with some form of security administration and management system . The aim of said invention is to optimally improve chipboard security by preventing fraudulent controls by a cryptographic processor or processors which use external signals for disturbing the normal operation of a processor or processors . The inventive security module IC component comprises at least two CPU A and CPU B processors , each of which is connected to ROM A and ROM B program memories , to programmable non-volatile and erasable data-containing memories ( EEPROM ) EEPROM A and EEPROM B and to random access memories ( RAM ) RAM A , RAM B for temporary storing data during processing , wherein the first CPU A processor comprises a bus for interfacing with the external of the IC component , the second CPU B processor is connected to the first CPU processor by means of a forwarding memory DPR , the non-volatile programmable and erasable memory EEPROM A of the first CPU A processor has a read access R only thereto and the second CPU B processor is provided with a read/write R/W access to said non-volatile programmable and erasable memory EEPROM A of the first CPU A processor . A threat model is constructed and subsequently the basic techniques to deal effectively with these threats are analyzed . Then this paper presents a dynamic , extensible , configurable and interoperable security architecture for multi-agent systems applied to security assessment services . It is explained how this architecture can be used to tackle a big part of security threats . Elliptic curve cryptography and secret sharing scheme present the main topics referred to in the proposed protocol . This coupling strengthens the eMRTD security , data storage and the authentication of both ePassport and its bearer . The Spi calculus is an adequate formalism to model cryptographic aspect of such electronic protocol and allows us to verify its properties .

For the characteristics of high speed mobility of nodes , frequent changes of dynamic topology and frequent interrupts of the communication links in the VANET , this paper analyzed the defect of the current mobile ad-hoc network routing protocol , and carried on the simulation analysis on the adaptability of AODV , DSR and DSDV routing protocols in VANET applications in the VANET . Through the above research , this paper obtained the conclusion that the AODV routing protocol is more suitable for vehicular ad hoc network environment
In this paper , we design an access control mechanism for vehicular ad hoc network environment to enable only authorized vehicles to access data using attribute based encryption . The existing access control schemes are expensive in the sense that the ciphertext-length grows linearly with the number of attributes occurring in the access policy and the number of pairings needed for decryption is linear to the minimum number of attributes satisfying the access policy to decrypt a message .
Based on the characteristic of vehicle mobile ad hoc network , for the first time , this paper analyzes the unstable situations of routing in vehicular mobile ad hoc network from the point of routing fracture , then proposes a GPS-free routing protocol RSBA(Relative Stability Based AODV Routing Protocol),with vehicle 's relative stability as it 's auxiliary parameter in routing establish process . Simulation shows RSBA 's lower route broken rate and routing overhead , as well as it 's better performances in reducing packet drop rate compared with AODV in high node 's density urban vehicle environment and validates the correctness of the analytic strategy and conclusions of the stability of vehicle mobile ad hoc network .
This scheme uses velocity property as intertier 's handoff rule while uses the pilot signal strength as intratier 's handoff rule . From the simulation results , the conclusion is given that the new scheme not only ensures low handoff failure probability for high-speed mobile services but also enhances the capacity of hierarchical system , and optimizes the handoff performance for all kinds of services
The widespread introduction of white LEDs has brought an unprecedented opportunity to create a ubiquitous indoor visible light communication system . In order to satisfy the illumination requirements , signals from multiple LEDs are always superposed on the receiving surface which causes severe inter-cell interference and leads to a critical demand for cell identification for scheduling and handoff . In this paper , we propose a visible light cell identification ( VLCID ) scheme based on cumulative space time coding ( CSTC ) to solve this problem .
However , to improve the scalability of our architecture , we have designed an efficient distributed Middleware Service layer that properly maintains application session handoff semantics while being able to service a large number of clients . We show that this service layer improves the scalability of general client-to-application server interaction as well as the specific case of application session handoff . We detail protocols involved in performing handoff and analyse an implementation of the architecture that supports the use of a real medical teaching tool .
Middleware layers placed between user clients and applicationservers have been used to perform a variety of functions . Inprevious work we have used middleware to perform a new capability , application session handoff , using a single Middleware Server toprovide all functionality . However , to improve the scalability ofour architecture , we have designed an efficient distributedMiddleware Service layer that properly maintains applicationsession handoff semantics while being able to service a largenumber of clients .
In this paper , we focus on the handoff scenario in which there is a need to relocate ( or provision ) certain application-specific functionality to ensure the seamless continuation of the user 's application after handoff . We provide a solution framework called the application context transfer ( ACT ) framework to address this need and describe its application to such handoff scenarios .
TCP being an end-to-end protocol has performance problems as its behaviour depends on the end-to-end path characteristics which are likely to be affected by a vertical handoff . We carry out a systematic study of TCP behaviour and the consequent problems that arise in various handoff scenarios between networks with different bandwidth and delay characteristics . This study can serve as a basis to evaluate any modifications to the TCP algorithm to adapt to a vertical handoff .
The mobility support of mobile terminals in a mixed IPv4/IPv6 environment remains largely unexplored .

This paper studies the buffer control issues that are related to supporting a seamless stream handoff in a WLAN environment that employs simulcast streaming . We analyze the impacts of the handoff disruption period and inter-AR synchronization variance . We also derive theoretical results that concern how a seamless stream handoff can be guaranteed in terms of the minimum buffer and backlog requirements . Based on the results , an MH-controlled-AR-pushed buffer control scheme is proposed and its cooperation with FMIPv6 is also discussed .
One of the prominent issues these days is the support for heterogeneous handoff . Different types of network come with high end data rates for rapid data transmission .
Due to the popularity of the IEEE 802.11-based LANs and fast development of the IEEE 802.16e MANs , we can expect a heterogeneous network consisting of 802.11-based and 802.16e networks in the near future . In such an environment , heterogeneous handoff is possible . How to keep guaranteeing the handoff connection its QoS demand , and in the meantime , avoid impacting on other connections is a challenge to support real-time applications in a heterogeneous network .
In this paper , we introduce a subclass of fractional channel policy , called uniform fractional channel policy ( UFC ) and study its performance . Expressions for both dropping probability of handoff calls and blocking probability of new calls are derived . Then it is shown that there is an optimal value for the parameter of UFC , which minimizes the blocking probability of new calls with the constraint on the upper bound on the dropping probability of handoff calls .
The theme of this thesis is the advancement of IP mobility management mechanisms to support robustly the delay requirements of interactive IP applications services . Current IPv6 mobility management standards are heavily dependent on reactive manipulations of the IP handoff process . Such modus operandi appears to be insufficient to address delay transparency during interactive IP communications .
On the other hand , the emerged concept of edge mobile computing has gained crucial attention by researchers that could help in reducing computational complexities and decreasing communication delay .

The outcomes are evaluated and contrasted with the network mobility method , our proposed technique , and other cluster-based technologies .
The location information of sensor nodes is utilized to achieve the IPv6-address configuration algorithm and the routing algorithm . In the mobility handoff algorithm , neither does a mobile sensor node need a care-of address during the mobility process , nor is involved in the mobility handoff process . Therefore , a mobile sensor node 's power consumption is reduced and the life span is prolonged .

We propose to utilize the filtered Gaussian phase dither technique for the effective suppression of the multipath- interference ( MPI ) noises caused by multiple bad fiber connectors in the mobile fronthaul network ( MFN ) based on the radio-over- fiber ( RoF ) technology . We first evaluate the viable performances of the RoF-based MFN in the 5 G wireless communication systems by using this technique and deduce the required bandwidth and phase modulation depth of the filtered Gaussian dither signal for the suppression of the MPI noises by numerical simulations . The results show that , by using the proposed technique , it is possible to suppress the MPI noises by ∼10 dB regardless of the number of bad fiber connectors .

This is a promising computing model especially in the context of Big Data . However , renting computing capabilities from a cloud provider means the integration of external resources into the own infrastructure and this requires a great amount of trust and raises new data security and privacy challenges . With respect to these still unsolved problems , this work presents a fixed vertical partitioning and distribution approach that uses traditional relational data models and distributes the corresponding partitions vertically across different cloud providers .
However for data to be used to their full power , data security and privacy are critical . Even though data security and privacy have been widely investigated over the past thirty years , today we face new difficult data security and privacy challenges . Some of those challenges arise from increasing privacy concerns with respect to the use of data and from the need of reconciling privacy with the use of data for security in applications such as homeland protection , counterterrorism , and health , food and water security .
