An Extensive Survey on different Routing Protocols and Issue in VANETs
Vehicular Ad Hoc Networks is a class of mobile Ad hoc Network. Vehicular Ad Hoc Networks (VANET) and mobile Ad hoc Network (MANET) are wireless networks which are points as automatic configured and self governing wireless adhoc networks. In VANET some terms of dynamic and high mobility are defined. Knowledge of routing in Vehicular Ad Hoc Networks becomes arduous and challenging due to changeable connectivity, high point mobility and network Distribution. The review paper tries to describe VANET and its routing protocols which focus on vehicle to vehicle (V2V) and vehicle to infrastructure (V2I). The objective of this study is to categorize protocols on the basis of routing information and comparing them using following parameters namely methodology used, advantage/power and limitations. The survey paper is located on routing protocols which are categorized as topology and position based routing protocols. This paper prescribes the comparison of reactive and proactive routing protocols based on their merits and demerits.
