Modified AODV Routing Protocol For Ad hoc Network

A Vehicular Ad-hoc Network (VANET) is a type of Mobile Ad-hoc Network (MANET) that is used to provide communications between nearby vehicles, and between vehicles and fixed infrastructure on the roadside. Though VANET is a type of MANET but the routing protocols of MANET are not feasible with VANET and if they are even feasible then they are not able to provide the optimum throughput required for a fast changing vehicular ad-hoc network. The difference between VANET and MANET is that in VANET, the nodes are moving on predefined roads, and node in the network is very fastly movable and this is where the routing protocols have to be modified or changed. The book presents the Vehicular Ad hoc Networks and the typical routing protocol: the ad hoc on-demand routing protocol (AODV) in mobile ad hoc networks and the modified protocol AODV_OBD for protocol AODV.
