A Contention-Based Routing Protocol for VANET
Abstract: In VANETs, vehicles
as nodes are self-organized and inter-communicated without centralized authority.
The topology formed by vehicles changes quickly, which makes routing become
instability.Position-based routing, compared with traditional routing, is more
scalable and feasible. Thus it has been proven stabler for VANETs than
conventional routing. However, the frequently changed topology and nodes
density could break the path a packet is following. Thus designing a robust
multi-hop routing in VANET is challenging. This paper proposes an enhanced
position-based routing protocol called CBGR, which takes into account the
velocity and direction of vehicles in VANET. Simulation results show that CBGR
achieves a high level of routing performance in terms of hop counts, network
latency and packet delivery ratio both in dense or sparse vehicular ad-hoc
networks.
