CBAODV: An Enhanced Reactive Routing Algorithm to Reduce Connection Breakage in VANET

Vehicular ad hoc networking (VANET) is a network that helps a vehicle to send information to nearby vehicles, and messages can be routed from vehicle to vehicle. In VANET, connection breakage (CB) is an important issue in the existing routing protocols such as ad hoc on-demand distance vector (AODV), DSR, and DSDV. In this paper, an enhanced reactive routing algorithm to reduce CB is proposed called as CBAODV based on AODV. The CBAODV allows route discovery and route maintenance, and it also reduces the CB. The experimental results are very promising as the proposed algorithm exhibits superior performance with respect to traditional AODV routing algorithm in terms of QoS metrics like end-to-end delay and packet delivery ratio. NS2 and MOVE tools are used as simulator to simulate the network and to prove the effectiveness of the research work.
