PCAR: A Packet-delivery Conditions Aware Routing Algorithm for Vanet Networks

Meimei Huo, Zengwei Zheng, Xiaowei Zhou and Jing Ying

Routing algorithm is an important research field for Vehicular Ad Hoc Network (VANET). The majority of current routing algorithms for VANET utilize indirect metrics (such as the distance or density of vehicles between source node and destination node) to produce optimal routing path but it is not sure that these indirect metrics can represent the real road conditions, so most of present algorithms remain at the stage of hypothesis. In this study, a packets-delivery conditions aware routing algorithm for VANET has been proposed with the purpose of using direct metrics to build a high quality route. It uses packet delivery ratio and average packet delay time as the metrics for calculating optimal route. The experimental results have shown that it outperforms GPSR and GPSR-L, in terms of average packet delay time, packet loss ratio and packet delivery ratio.
