一种基于GPSR协议的能量均衡路由

摘要

针对贪婪周边无状态路由(GPSR)协议存在的热点路由问题,提出了一种基于GPSR的能量均衡路由GPSR-EB.节点在路由选择过程中综合考虑邻居节点的能量水平和位置信息选择下一跳,从而使节点负载相对均衡,避免热点路由上节点的过早死亡和网络生存时间缩短.NS-2仿真结果表明:GPSR-EB在未影响数据包成功传递率的基础上实现了能量均衡,延长了网络生存时间.%Focusing on the hot-routing problem in traditional greedy perimeter stateless routing ( GPSR ) ,a new energy balancing greedy perimeter stateless routing ( GPSR-EB) is proposed. In routing discovery phase, intermediate node not only take the geographic location of its neighbor nodes into consideration, but also take account of their energy level , in order to get relatively balanced load among neighbor nodes, avoid the premature death of hot nodes or the network. Simulation results in NS-2 simulator show that the proposed GPSR-EB makes energy of nodes blanced and prolongs the network lifetime without affecting packet delivery success rate, compared to GPSR.
