A stable routing protocol using segment-by-segment way in VANET

Abstract

Vehicular Ad hoc Network (VANET) is a new technology which has attracted enormous attention recently. For the high mobility of vehicles, to design a stable routing protocol becomes an important issue. This paper proposes a Stable Routing Protocol (SRP) for highway scenario using segment-by-segment way. Each node in the SRP protocol maintains a k-hop vicinity routing table. When a source node and a destination node are in the same vicinity, it adopts proactive routing. Otherwise, the route is carried according to location-based way. Simulation studies show that the SRP protocol outperforms Greedy Perimeter Stateless Routing (GPSR) in terms of average path length and average packet delivery ratio. When node density is moderate, the SRP protocol consumes some acceptable routing overhead to achieve good performance.
