WSN中LEACH协议局限性的分析与改进
nalysis and Improvement of LEACH Protocol Limitation In WSN
由于无线传感器网络是一种能量、资源受限的网络，因此路由协议必须保证较小的路由开销并尽可能的减少能耗。本文在分析和研究现有无线传感器网络的路由协议的基础上，着重对经典分簇路由协议LEACH 算法进行详述与分析。基于LEACH算法动态随机选举簇首、簇首节点与sink节点直接通信等特点，本文引入对簇首节点之间通信采用多跳路由转发的考虑，对LEACH算法进行了部分改进，并对改进后的算法作了充分的理论性分析及模拟仿真。
Because the wireless sensor network is one kind of energy-limited and resource-limited network, the routing protocol must guarantee the smaller routing expenses and the reducing energy consumption. Based on the analysis and research of existing wireless sensor network routing protocol, this paper emphasizes on the detailed description and analysis of the classic hierarchy routing protocol LEACH algorithm. The paper also introduces the consideration of the multi-hop routing repeater among the cluster head nodes and partly improves the LEACH algorithm, furthermore makes the theoretical analysis and the simulation of the improved algorithm.
