摘要
基于GPSR协议提出一种新的车载网路由协议,该协议能很好的适应车载网中车辆节点高速移动的特性,降低道路间障碍物对数据传输的影响,并能根据车流密度自动调节数据包的流向,从而提高路由协议的连通率;同时,新的路由协议也能够自动区分乡村高速公路、城市路况等不同的道路环境,并依据不同的路况采用不同的策略进行数据的传输。仿真结果表明,新协议的连通率明显高于GPSR协议。
In this paper we propose a new routing protocol based on GPSR protocol. The new protocol can be well adapted to the characteristics of high-speed mobile vehicles in VANET,and it can also reduce the influence of the obstacles for data transmission between different roads. In addition to this,the new protocol can automatically according to traffic density to adjust the flow of data packets,so as to improve the connectivity rate. Furthermore,new routing protocol can also automatically distinguish the rural highway,urban road conditions so that it can adopt different strategies for data transmission according to different road conditions. We do a lot of simulation experiments for this new protocol,and the result shows that the Connectivity rate of the new protocol was obviously higher than that of GPSR protocol.
