Handling Video Conferencing ( VC ) services is currently a vast challenge in the communication industry . Wireless networks have been designed to provide provision for real-time applications such as VC . VC QoS metrics should be evaluated for different IEEE 802.11 technologies in order to identify the optimum technology standard across different infrastructure and network architectures . CR can scan the spectrum band and identify free channels which will be used by cognitive users with no harm to primary users . Due to the various dynamic characteristics of Cognitive Radio Networks ( CRN ) , adaptation and secure communication are of greater significance than other wireless networks . In this paper , we propose an adaptive trust management mechanism based on cognition cycle , which can mitigate system error rate effectively and make spectrum allocation more reasonable and secure . Higher frequencies may be used by 5 G , but the result is high cost . Furthermore , the volumes of video traffic in wireless system networks , there is an urgent need for improving the quality of video delivery . For this reason , this paper is devoted to proposing a wireless mobile system based on the updated LTE-ADV Pro ( 4.5G–4.9 G ) technology to arrive 5 G capability with low cost . In environment the wireless system networks comparing with small devices which insufficient quantities of energy seriously keep under control for extremely important in operations . These kind of energy sources devices reduce quickly in fast continuous working for operating in crucial to put over a particular period of time in the power sources . This paper deals with a way to probabilistically guarantee reliable packet delivery in WirelessHART based networks suitable for industrial control systems . We propose a new scheduling scheme , called Iterative Probabilistic Scheduling with Adaptive Relaying ( IPS-AR ) , which consists of a static part ( IPS ) and a dynamic part ( AR ) . Routing in Mobile Ad Hoc Networking technology ( MANET ) is challenging due to its route discovery feature dealing with link failures and to repair the routes in these situations . An ad hoc network is a temporarily infrastructure less network in which nodes can join and leave the network at anytime and are free to move randomly and organize themselves arbitrarily . In MANETs , each node should not only work for itself , but should be cooperative with other nodes . The various routing protocols are analyzed and the advantages and disadvantages associated to particular protocol is briefly discussed . The contribution of this paper is to focus on comparative study of various routing protocol used in the ad-hoc network . Ad hoc networking is a wireless networking paradigm for self-organizing networks that until recently has mainly been associated with military battlefield networks . However , with the availability of wireless technologies such as Bluetooth and 802.11 and the development of the next generation networks , civilian applications that exploit the advantages of ad hoc networking are being envisioned . So far most of the research has been carried out to address the routing issues . Our proposed algorithms adapt existing AODV routing protocol to improve performance in terms of energy conservation and other performance metrics . The purpose of using energy metric as route select method is to improve lifespan of Ad Hoc communication network and corresponding effect on overall network performance . Simulation results indicate that the routing schemes are more efficient than existing well-known routing protocol . In order to solve the communication problems between clusters as well as achieve the goal of the high-precision flying of UAV clusters , a UAV formation realization using ad hoc network and fuzzy control technology was proposed . Firstly , Zigbee communication technology is used to set up an ad hoc network communication system that can achieve automatic networking , automatic routing , and dynamic maintenance . The custom data encoding format and specific complete encoding and decoding process are used to ensure the efficiency of ad hoc communication networks and the reliability of information transmission . Integrated remote meter reading system using a zigbee communication scheme according to the invention , By using the Zigbee communication module , the internal and direct frequency spread spectrum modulation method 1 : N or 1 : N : N ( where , N is the number of the integrated meter reading meter , 1 indicates the number of repeaters ) in communication with on-de mandrel ( On Demand ) integrated meter reading is possible to route the available Ad-Hoc network communication , and store the electricity , gas , water data in the home ; It built a Zigbee communication module , and a repeater for receiving meter data from the integrated meter reading ; A front-end processor including the features over the Internet network to receive transmission data from the repeater ; And comprises a remote meter reading a server that also includes a processor connected with the front-end functionality to receive forwarding the data , and calculates the charge on the basis of the data , and the data to determine whether the non-reading of data or an abnormal reading data . In addition , the integrated remote meter-reading method using a zigbee communication scheme according to the invention , Comprising the steps of : ( a ) a remote meter reading request , the server meter reading data by calling a Zigbee communication system modem within the integrated meter reading meter of the home through a front-end processor and the repeater ; ( B ) step of electricity , water and gas consumption data is stored in the integrated meter reading ; ( C ) 1 : N or 1 : N : N ( where , N is the number of the integrated meter reading meter , 1 indicates the number of repeaters ) in communication with on-de mandrel ( On Demand ) routing is made of a possible Ad-Hoc network communication system step incorporated metering weighing period passes the inspection data is finally transmitted to the repeater ; And ( d ) in which the data is transmitted to the front-end processor through the internet , the transfer back to the remote meter reading server ; ( E ) a remote server comprising : reading the meter reading data to determine whether the non-inspection or an abnormal reading data ; And ( f ) when reading data in a non-inspection or non-abnormal reading data in the above step , a step that we calculate the fee based on the data . Remote meter reading , meter reading , ZigBee ( ZigBee ) These limitations can be overcome through offloading execution and distributing computation execution on to more resourceful devices . This paper proposes a solution to execute Android applications through a mobile ad hoc network formed by devices in the proximity . The mobile ad hoc network is formed using Wi-fi Direct technology that enables fast and seamless communication . Mobile wireless ad hoc networks are instantaneous , autonomous telecommunication networks that provide service to users wherever and whenever the service is needed . The communication depends on wireless links that are formed between the users . In this paper , we propose three hybrid recovering algorithms , namely , cascade movement based on nearest nodes , cascade movement based on connected dominating set , and cascade movement based on critical nodes . With the adoption of Kalman filter , all these schemes can predict the movement of nodes so as to identify and maintain connectivity of mobile wireless ad hoc networks . Meanwhile , once a node fails or a link breaks down , they can also recover the connectivity immediately . Application for wireless networking has been evolving rapidly and is becoming an integral part in our everyday life . Also with the recent performance advancement in wireless communication technologies , mobile wireless ad-hoc networks has been used in many areas such as military , health and commercial applications . Mobile ad hoc networks utilize radio waves and microwaves to maintain communication channel between computers . Due to instability of links in the network , the model of delay tolerant networks ( DTNs ) is often adopted in many emerging mobile applications . To organizations and individuals using these mobile applications , security and privacy are considered to be two of the most significant concerns . In Delay Tolerant Networks ( DTNs ) , nodes seldom keep in contact with each other because of the disorder movements of nodes . Thus many traditional routing protocols may not be applicable in this emerging network . Delay tolerant networks ( DTNs ) have become a promising solution for extending Internet boundaries to challenged environments such as satellite constellations . In this context , strategies to exploit scarce communication opportunities , while still considering device and application constraints , are still to be investigated to enable the actual deployment of these networks . We perform an extensive evaluation of our algorithms by varying both the underlying routing and mobility models . Our results suggest several findings to guide the design and operation of throwbox-augmented DTNs However , current related works ignore the influence of the energy constraint on the routing . In this paper , we investigate the performance of routing schemes for the energy-constrained DTNs . First , we model the two-hop relaying , epidemic routing and K-hop forwarding with energy constraint based on a two-dimensional continuous time Markov chain . They are designed to overcome high latency and lack in connectivity due to poor infrastructure and short range radios . However , the DTNs relay nodes have limited resources ( i.e. , low-power RF module , low computation capacity , limited buffer size , short battery power ) . Moreover , the DTNs routing protocols , which route the message between a source and a target destination , are very numerous , including the famous Epidemic routing , k-hop routing , prophet routing . CHANTS provides an ideal venue for researchers and engineers to present cutting-edge work and results in the field of challenged networks . The workshop solicited papers and demos addressing the following topics : Delay/disruption-tolerant networks ( DTNs ) Architecture , design , implementation , and evaluation of communication systems for challenged networks Case studies involving real challenged network solutions in various stages of development or use Analysis and characterization of challenged networks and protocols Applications in challenged networks ( disaster relief and emergency management , vehicular networks ) Configuration , management , and monitoring of challenged networks Security/Privacy concerns and solutions in challenged networks Real-world mobility traces of challenged environments Test and simulation tools for evaluating challenged network systems Applications challenged networking techniques to communication in daily life CHANTS received 32 submissions and each paper was reviewed by at least 3 referees . After careful consideration of all of the submitted papers , the CHANTS 2012 Technical Program Committee selected eleven high-quality research papers ( eight full papers and three short papers ) , five demos and five posters covering diverse topics . Because of the low node density , high mobility and short radio communication range , a complete path between the source and the destination may not exist . In bus-based DTNs , the buses move following the scheduled trajectories and are equipped with devices which provide two kinds of communication , including short-distance communication and long-distance communication . This paper studies the energy efficient multicast routing problem with delay constraint for each destination . The monolithic SRN model proposed in the first step is not scalable , in terms of the number of communities and nodes , due to the state space explosion in the underlying Markov chain . In order to solve the scalability problem of the monolithic model , an approximate model based on the folding technique is presented which allows us to evaluate the performance of large-scale DTNs . In order to cross-validate the results obtained from the proposed models , we extend the ONE simulator to support our network model . Vehicular Delay-Tolerant Networks ( VDTNs ) use vehicles to transfer data between nodes , enabling network connectivity in sparse or partitioned opportunistic networks , where the low node density contributes to an absence of end-to-end links . By implementing a DTNs store-carry-and-forward paradigm , VDTNs allow delay-tolerant data traffic from a variety of vehicular applications to be routed over time , such as , but not limited to , information queries and context-specific broadcasts . Network Management adopts a key function in the well being of any communication network . The project involved development , integration , and deployment of delay-tolerant networks ( DTN ) and applications in remote areas . The simulation tool supports system integration and testing by connecting real and virtual hardware and software network nodes via DTNs simulated with the aid of the ns-3 network simulator . The examples shown illustrate node discovery and message transport - direct as well as using a data mule service . However , because of battery limitations on mobile devices , it is often the case that not all messages can be delivered . In this paper , we propose a new approach for priority-scheduling in participatory DTNs , whereby both message 's value to the end-user as well as the likelihood of future encounters are combined to make the forwarding decision . For completion , we present , in Fig . [ reference ] results obtained by performing domain transfer using DTNs in the reverse direction of the one reported in Sec . [ reference ] . Current position location techniques such as TDOA suffer from multipath effects , which reduces the estimation accuracy . In this paper we propose time-reversal in a wireless communication network , where a mobile terminal wants to determine , through feedback , its own position in the request of the base station . The proposed method improves the estimation accuracy and reduces the estimation variance compared with correlation based method . The invention provides an environment monitoring system . The environment monitoring system comprises at least one base station , at least one monitoring device and a monitoring control device ; information is transmitted among the monitoring control device , the monitoring device and the base station through a wireless communication network , the monitoring control device is provided with a monitoring command and sends the monitoring command to the monitoring device in the form of short message via the base station through the wireless communication network , and the monitoring device senses environment data according to the monitoring command and sends the environment data to the monitoring control device in the form of short message via the base station through the wireless communication network . Therefore , this paper investigates the effect of using WirelessHART network on the control performance of pilot flow plant . The plant will be controlled using PI , PID and Fuzzy PID controllers both wired and over WirelessHART network . Experimental results of the controllers shows that , the performance of these controllers is degraded when the control is done over WirelessHART network . In this paper we first study if we can establish a WirelessHART control loop the same way as a wired one ; then we study if our WirelessHART control loop could achieve the same execution rates and reliability as a wired Foundation Fieldbus control loop . The experiment affirms that , in most likely cases , control over a WirelessHART network could be as good as control over a wired fieldbus .

Optimization of the access point layout is one of the issues in the field of networking . This issue is relating to the layout of access point on the Wireless Fidelity ( Wi-Fi ) network that requires theoretical consideration and analysis . Because of these requirements , a good mechanism is applied in the minimizing aspects between both cost and time on the implementation of WiFi network that used by network designer to organize the layout of the access points in the proper place . A method for initiating a Wi-Fi voice service , an LTE communication device , a terminal , and a communication system ; a long-term evolution ( LTE ) network communication device receives IP address information of a preset evolved packet data gateway ( ePDG ) ; the LTE network communication device sends the ePDG IP address information to a terminal by means of the LTE network ; the terminal , in a wireless fidelity ( Wi-Fi ) network , and on the basis of the ePDG IP address information sent previously by the LTE network communication device , establishes a communication link with the corresponding ePDG , and initiates a Wi-Fi voice service by means of the ePDG having said communication link .

However , the DTNs relay nodes have limited resources ( i.e. , low-power RF module , low computation capacity , limited buffer size , short battery power ) . Moreover , the DTNs routing protocols , which route the message between a source and a target destination , are very numerous , including the famous Epidemic routing , k-hop routing , prophet routing .
CHANTS provides an ideal venue for researchers and engineers to present cutting-edge work and results in the field of challenged networks . The workshop solicited papers and demos addressing the following topics : Delay/disruption-tolerant networks ( DTNs ) Architecture , design , implementation , and evaluation of communication systems for challenged networks Case studies involving real challenged network solutions in various stages of development or use Analysis and characterization of challenged networks and protocols Applications in challenged networks ( disaster relief and emergency management , vehicular networks ) Configuration , management , and monitoring of challenged networks Security/Privacy concerns and solutions in challenged networks Real-world mobility traces of challenged environments Test and simulation tools for evaluating challenged network systems Applications challenged networking techniques to communication in daily life CHANTS received 32 submissions and each paper was reviewed by at least 3 referees . After careful consideration of all of the submitted papers , the CHANTS 2012 Technical Program Committee selected eleven high-quality research papers ( eight full papers and three short papers ) , five demos and five posters covering diverse topics .
Because of the low node density , high mobility and short radio communication range , a complete path between the source and the destination may not exist . In bus-based DTNs , the buses move following the scheduled trajectories and are equipped with devices which provide two kinds of communication , including short-distance communication and long-distance communication . This paper studies the energy efficient multicast routing problem with delay constraint for each destination .
The monolithic SRN model proposed in the first step is not scalable , in terms of the number of communities and nodes , due to the state space explosion in the underlying Markov chain . In order to solve the scalability problem of the monolithic model , an approximate model based on the folding technique is presented which allows us to evaluate the performance of large-scale DTNs . In order to cross-validate the results obtained from the proposed models , we extend the ONE simulator to support our network model .
Vehicular Delay-Tolerant Networks ( VDTNs ) use vehicles to transfer data between nodes , enabling network connectivity in sparse or partitioned opportunistic networks , where the low node density contributes to an absence of end-to-end links . By implementing a DTNs store-carry-and-forward paradigm , VDTNs allow delay-tolerant data traffic from a variety of vehicular applications to be routed over time , such as , but not limited to , information queries and context-specific broadcasts . Network Management adopts a key function in the well being of any communication network .
The project involved development , integration , and deployment of delay-tolerant networks ( DTN ) and applications in remote areas . The simulation tool supports system integration and testing by connecting real and virtual hardware and software network nodes via DTNs simulated with the aid of the ns-3 network simulator . The examples shown illustrate node discovery and message transport - direct as well as using a data mule service .
However , because of battery limitations on mobile devices , it is often the case that not all messages can be delivered . In this paper , we propose a new approach for priority-scheduling in participatory DTNs , whereby both message 's value to the end-user as well as the likelihood of future encounters are combined to make the forwarding decision .
For completion , we present , in Fig . [ reference ] results obtained by performing domain transfer using DTNs in the reverse direction of the one reported in Sec . [ reference ] .

In order to support high data rate requirements and effectively manage the scarce wireless resources , additional bandwidth channels are allocated and taken away from mobile stations in 3 G wireless data networks quite frequently . A TCP sender connected to the mobile , on seeing ACKs coming at a faster pace after additional bandwidth allocation , turns overtly optimistic and injects data into the network at a rate that might be excessive for an intermediate router , thereby leading to loss of multiple packets and subsequent prolonged recovery and periods of underutilization .
