摘要: As it is a big challenge to adapt routing protocol different applications and dynamic network topology in Mobile Ad Hoc Networks, geographic protocols such as Greedy Perimeter Stateless Routing (GPSR) have attracted significant attention. However, unintelligent path selecting strategy outdated neighbor information lead unwanted performance decline. In this paper, we propose called Crossroads Optimal Geographic (COGR) for vehicular ad hoc networks (VANET) city scenario, which features on intelligent planning, efficient recovery from dead holes feasible position distribution without map ahead. Through simulation experiments, prove that COGR does substantially improve packet delivery ratio, delay throughput highly environment VANET scenario.
