Stability Based Routing Scheme for Vehicular Networks

The vehicles are significant entities inside a vehicular network, capable of exchanging safety and non-safety messages with the neighbouring vehicles and RSU (road-side unit). The rapidly changing connectivity, error prone wireless channels, and low vehicle density in vehicular networks can make the routing schemes perform less efficiently. It leads to two main issues: to find the best routing strategy, to adapt the routing scheme in challenging settings of vehicular networks. In this paper, we propose a scheme to construct a stable path between source and destination node by using route request and route reply packets to ensure better packet delivery ratio, lower end-to-end delays and reduced message overheads. On the basis of simulation results, we conclude that the distance parameter or the traffic model alone may not be sufficient to derive the stability factor of any link and should be incorporated with the stability factor derived from the propagation model.
