煤矿巷道无线传感器网络LEACH协议的改进

Improvement of LEACH Protocol of Wireless Sensor Network in Coal Mine Roadway

指出了随着信息技术的飞速发展,无线传感器网络已广泛应用于医疗、军事、环境检测、工业以及煤矿等领域。针对煤矿巷道狭长的地形特点,分析了LEACH路由协议应用于煤矿巷道的不足,在LEACH协议的基础上对其进行了改进,对竞选簇头的节点阈值函数进行了调整,加入了节点剩余能量、分布以及与基站的距离等因素。经过MATLAB仿真,验证了改进协议的优越性。

With the rapid development of information technology,wireless sensor networks have been widely used in medical,military,environmental detection,industry,and coal mining fields.In view of the long and narrow geographical characteristics of coal mine roadways,this paper analyzes the deficiencies of LEACH routing protocol applied to coal mine roadways.On the basis of LEACH protocol,the deficiencies are improved.The node threshold function of election cluster heads is adjusted.Node residual energy,distribution and distance from the base station are added.The superiority of the improved protocol is verified by MATLAB simulation.
