无线网状网中延长网络生命周期的机会路由
|
摘要
根据无线网状网的网络特征,以延长网络生命周期为目的,设计了一种结合节点剩余能量与地理位置信息的机会主义路由协议GEOR,并给出了一种基于跳数的节点通讯范围算法。实验仿真结果表明:相比于传统的路由协议Ex OR及以能耗为目的的路由协议PLOR,协议GEOR有效延长了网络生命周期,均衡了节点能耗。
According to the network characteristics of wireless mesh network,one opportunistic routing protocol( GEOR) which combines the residual energy of the node with the geographic location information is proposed to prolong the network lifetime. And a node communication range algorithm is presented based on hops. Simulation results show that routing protocol PLOR aims at energy consumption comparing with the traditional routing protocol ExOR,it effectively prolongs the network lifetime and balances the energy consumption of nodes.
