摘　　要：针对无线传感器网络的资源限制以及对传输可靠性的特殊要求,提出一种能量均衡路由度量方法EBETX。以ETX值作为路由度量的同时,兼顾网络中节点能量消耗情况,保证网络各节点能量均衡消耗,延长网络的生存时间,实现高效路由与能量均衡的有效权衡。通过NS2仿真实验验证了该方法的可行性。Aiming at the limited energy and the special requirement of transmission reliability for Wireless Sensor Network（WSN）, an energy-balanced routing metric measure method, EBETX is proposed,. This method avoids the data packet transmit along the lower energy path, and selects the path which has more surplus energy. It makes the energy of the nodes in the network keep balance. Simulation results by NS2 show that this method can prolong the life time of the network and implement the effective balance of transmission reliability and energy balance.
