Abstract: In order to prolong the life time of the network and ensure energy balance of the wireless sensor network, a novel routing algorithm of wireless sensor network based on optimal connectivity power is proposed in this paper to solve the deficiencies of LEACH algorithm. Firstly, the optimal neighbor set are chosen according to the optimal connectivity power, and then cluster head is selected according to the node residual energy and communication mode of inter cluster adaptively, finally the performance is test by simulation experiments on Matlab 2012. The simulation results show that the proposed algorithm has solved the node energy imbalance problem and improved the energy utilization of the network.

摘要： 为了延长网络生存时间，保持节点的能耗平均衡，提出了一种最优连通功率的无线传感器网络路由算法。首先根据最优连通功率选择最优的邻居节点集合，然后根据节点剩余能量选择簇首，并采用自适应的簇间通信方式，最后在Matlab 2012工具箱进行仿真测试。实验结果表明，相对于当前经典路由算法，提出的最优连通功率路由算法解决了传感器节点耗能不均衡难题，提高了无线传感器节点的能量利用率。
