摘    要:贪婪周边无状态路由协议(GPSR)在Ad Hoc和传感器网络中有广泛的应用,GPSR的路由是以距离目的坐标最近的原则进行选路的,容易形成热点路由,从而缩短网络的生存时间。基于对邻居传感器节点的能量感知,提出了有动态负载均衡能力的GPSR路由算法。该算法能够根据网络节点的能量情况动态调整路由。仿真结果表明提出的具有动态路由负载均衡能力的GPSR算法能有效延长网络的生存时间。

关 键 词:贪婪周边无状态路由协议(GPSR)  负载均衡  能量感知

Abstract:Greedy Perimeter Stateless Routing(GPSR) has been used widely in Ad Hoc and sensor networks.The algorithm is based on geographical information, in which the current node always forwards a message to its neighbor node that is closest to the destination.This algorithm reduces the lifetime of sensor network when there exist hot sources.An energy-aware dynamic load balance routing algorithm is proposed to improve GPSR.The proposed algorithm dynamically adapts routing to node energy.The simulation results prove the proposed method can prolong sensor network lifetime efficientry.
Keywords:Greedy Perimeter Stateless Routing(GPSR)  load balance  energy-aware
