摘　　要：近年来随着我国森林面积的逐步扩大,对于森林的保护,也成为国家和社会关注的重点。加强森林防火工作是林业问题中的重中之重。针对护林防火监测中的问题,传感器网络提供了很好的解决方案。在本文中,阐述了1种应用于护林防火的改进的无线传感器网络算法,该算法是基于LEACH算法的改进算法,称为LEACH-HD。该算法通过推导一阶无线能量模型,得到最佳簇首数目,通过加入节点的剩余能量因子和节点与主机节点的平均距离因子,改进簇首节点的选择方式。仿真结果表明,LEACH-HD算法能够提升节点的存活时间,数据接收量,降低网络能耗。In recent years,with the gradual expansion of China's forestry area,the protection of forests has also become the focus of national and social concern.Strengthening forest fire prevention is the top priority in forestry issues.Aiming at the problems in forest protection and fire prevention,sensor networks provide a good solution.In this article,we describe an improved wireless sensor network algorithm applied to forest protection and fire protection.The algorithm is an improved algorithm based on LEACH algorithm,called LEACH-HD.The algorithm obtains the optimal number of cluster heads by deriving the first-order wireless energy model,and improves the selection method of cluster head nodes by adding the remaining energy factor of the node and the average distance factor between the node and the host node.Finally,the simulation results show that the LEACH-HD algorithm can improve the survival time of nodes,the amount of data received,and reduce network energy consumption.
