摘　　要：提出了一种TBPR(time-based broadcasting for power-aware routing)协议.TBPR采用路由请求报文延迟发送机制,并通过比较路径中的累计功率消耗,选择能量消耗较低的路由,以降低网络的能量消耗,延长网络的生存周期.计算机仿真实验表明,TBPR能够取得较好的节能效果,并降低无线AdHoc网络中的能量消耗.A TBPR （time-based broadcasting for power-aware routing） protocol is proposed. Since more hops can save more energy in wireless transmission, the TBPR protocol selects more energy efficient routes by comparing accumulated power consumption based on the mechanism of delaying rebroadcast route request packets. This method can reduce energy consumption and prolong the lifetime of network. Simulation results indicate that the TBPR protocol can conserve more energy and reduce energy consumption in wireless Ad hoc networks.
