摘　　要：传统自组网路由协议设计通常不考虑路由开销带来的能量消耗问题,而在能量受限的无线通信终端上,一旦能量耗尽,节点将"死亡",从而影响整个网络性能。本文设计了一种改进型OLSR路由协议,在MPR节点选取上,引入能量代价函数,保证各节点能量的均衡使用;在实现上改进HELLO和TC消息,采用次优多跳路由策略,减少路由开销带来的能量消耗。仿真实验结果表明,改进型混合路由协议能够明显延长整个网络的生存时间。The design of traditional ad hoc protocols usually ignores the energy consumption caused by routing. Due to the wireless communication terminal with limited energy,once the energy is exhausted,the nodes will die,which will affect the performance of the whole network. In this paper,an improved OLSR routing protocol is designed. The energy cost function is introduced into the selection of MPR nodes to ensure the balanced use of energy in each node. The HELLO and TC messages are improved and the suboptimal multi hop routing strategy is adopted to reduce the energy loss caused by routing overhead.Simulation results show that the improved hybrid routing protocol can significantly prolong the lifetime of the whole network.
