A Survey of Routing Algorithms in Vehicular Networks

Vehicular Ad hoc Network (VANET) is an advanced style and subcategory of a Mobile Ad hoc Network (MANET), the main objective of VANET's is to create an Intelligent Transport System (ITS). The routing in VANET has attracted many attentions during the last few years. Highly mobility of vehicles, irregular communication between the vehicles and the necessities of real time applications are some of the major challenges of multi-hop message delivery in VANETs. Because of the frequent changing topology of VANET it becomes difficult to route the packets effectively. In this research, we are focusing on the routing concept for the VANET i.e. principles for routing, decomposition of the routing function and requirement for Forwarding protocols unicast (Geographic based, Trajectory based and Link Stability based) and Probabilistic (Distance based) routing protocols in VANETs, To analyse the performance of the most suitable routing protocols and to determine the best efficient protocol for VANET environment.
