Improved AODV routing protocol for vehicular Ad hoc networks

Vehicular Ad hoc networks are one of the most advanced technologies for intelligent transportation system that allow vehicle-vehicle to form multi-hop ad hoc networks. Routing is one of the challenges in vehicular ad hoc networks because of the frequent change of its topology structure. In this paper, we propose a routing protocol (AODV_BD) for vehicular ad hoc networks that improves the Ad hoc On-Demand Distance Vector (AODV) routing protocol by making it reduce the packet delay. The simulating experiments provide an efficient approach to estimate the routing protocol performance of a VANET.
