| 摘 要： | 根据位置服务信息,采用道路内微观路由和道路间宏观路由相结合的路由方案(MiMa),引入Dijk-stra优化算法为节点间通信提供一条具有导向功能的最佳路由。实验结果表明,该路由协议提高了数据包投递率,降低了数据端到端的传输延迟。

| Abstract: | A routing protocol based on position service information is proposed which adopts the cooperation of micro-scale routing within a road limits and macro-scale routing between roads for VANETS.The optimized Dijkstra algorithm is employed to calculate an oriented optimum route for source and destination.The simulation results show that the proposed protocol enhances the throughputs and reduce the end-to-end delay. |
