摘要
针对无线传感器网络贪婪地理路由协议中的路由空洞问题,分析了现有路由空洞解决策略的不足,对GPSR路由协议中边界转发策略进行改进,提出了一种左、右手法则相结合的分区边界转发策略。仿真结果表明,改进后的协议能够以较小的控制开销代价,提高数据包投递成功率,减少路由跳数,提高贪婪地理路由协议的实时性。
To handle routing void problem of greedy geographic routing protocol in wireless sensor networks,this paper analyzed shortages of methods which dealt with the routing void,improved the perimeter forwarding strategy in GPSR,and proposed a regional perimeter routing based on right and left-hand rules.The results of simulation indicate that the improved protocol can improve the packet delivery success rate,shorten routing path length,and improve the real-time capability of greedy geographic routing protocol.
