为了提高大型无线传感器网络的稳定性，延长网络的整体寿命，以 WSN分簇路由协议LEACH为基础，提出一种新的簇头选举方法。算法利用网络寿命预测模型，首先预测网络节点死亡时间，然后将文中定义的网络收敛速率引入优化算法中得到最优簇头数目。仿真结果表明，优化后的算法相比于LEACH算法能耗显著减少，有效地延长了网络的寿命。

In order to improve the stability of large-scale wireless sensor networks and prolong the overall lifetime of WSNs, this paper proposes a new method for cluster head election based on LEACH.First, the algorithm uses the network lifetime prediction model to predict the time of death of the network node.Then define the network convergence rate, and use it to calculate the optimal cluster head size.Simulation results show the effectiveness of the improved algorithm and prove the improved algorithm is much better than LEACH in energy consumption and lifetime.
