| 摘 要： | 针对LEACH协议在簇头选取、数据通信方面的不足，提出改进后的AD-LEACH协议。根据节点的分类，修正簇头当选概率，使簇头选取均衡了能耗、距离、节点密度的影响。通过节点位置模糊匹配的方法将全网划分为若干个均匀大小的网格。数据传输阶段以能量利用率最高为目的，基于最佳转发距离选择转发节点。仿真结果表明，AD-LEACH协议有效降低和均衡了网络能耗，达到了能耗最优的目的。

| Abstract: | To overcome the shortage of electing of cluster head and data transmission method in LEACH protocol, AD-LEACH protocol is proposed after improving. Based on different categories of nodes, the probability of being cluster head is modified to balance the influence of energy consumption, distance and node density. WSN is divided into several grids sharing the same size through fuzzy matching node positions. During the course of data transmission, the relaying node is selected with optimum distance and the minimum energy and consumption. The simulation results show that AD-LEACH protocol balances the energy consumption of WSN effectively and achieves the purpose of the optimal energy consumption. |
