摘　　要：路由能耗直接影响无线传感器的寿命,针对当前无线传感器网络路由算法存在的能量利用率低、严重不均衡等难题,设计了一种基于考虑剩余能量和通信代价的传感器网络路由算法。该算法首先从簇首选择问题入手,全面考虑所有传感器节点剩余能量进行簇首选择和竞争,选择最优传感器节点作为簇首,防止剩余能量最少的传感器节点成为簇首;然后选择通信代价小、剩余能量多的传感器作为通信的中继节点,均衡各节点的能耗,最后采用仿真工具NS2对路由算法的性能进行测试与分析。测试结果表明,该路由算法减少了无线传感器通信的能量消耗,延迟了传感器节点的死亡时间,改善了能量的有效性。Energy consumption of routing directly affects the wireless sensor network life,but the existing wireless sensor network routing algorithm has low energy utilization,serious imbalance problem. This paper designs a wireless sensor network routing algorithm based on energy balance.Firstly,comprehensive consideration of the residual energy of cluster head selection and competition of all the sensor nodes,optimal selection of sensor nodes is selected as cluster heads to prevent the least residual energy of sensor nodes to become cluster head;and secondly,the sensor with low communica-tion cost and more residual energy is selected as relay communication node to balance energy consumption of each node;at last the performance of the routing algorithm is tested on simulation tool NS2. The test results show that the proposed routing algorithm reduces the energy consumption of wireless sensor communication,delays the death time of sensor nodes,and improves the effectiveness of energy.
