矿井长直巷道中WSN的LEACH路由协议研究

摘要

LEACH路由协议具有层次化、自组织分簇的优点。本文针对矿井长直巷道环境下LEACH协议的不足，提出一种可靠的能量均衡路由算法LEACH-TLLEB。该算法采用线性网络拓扑结构合理部署Sink节点，局部区域节点结合位置均衡和能量均衡选举簇头。仿真结果证明，该算法改善了矿井下长直巷道WSN网络的可扩展性和能耗不均衡等问题，延长了网络的生命周期。%LEACH routing protocol has advantages of hierarchical and self-organizing clustering. Aiming to improve the shortcomings of LEACH protocol in the environment of long straight mine roadway, this paper pro-poses a reliable energy balanced routing algorithm LEACH-TLLEB which uses linear network topology structure to deploy the sink nodes rationally, and uses the local nodes to elect cluster head nodes with equilibrium position and energy balance. The simulation results show that this algorithm can improve the scalability of WSN in mine long straight tunnel and energy balance and other issues, and reduce the average energy consumption in network.
