Application of an Improved DV￣Hop Localization Algorithm of Wireless Sensor Network to Leakage Fault of Underground Coal Mine
摘要
Abstract
The location of leakage fault is an important topic of power system protection in the real￣time monitoring of transmission lines of coal mine. An improved DV￣Hop localization algorithm is proposed in order to solve the problem of inaccurate localization for wireless sensor networks in the underground coal mine. Firstly,by calculating the triangle area of anchor nodes to eliminate the anchor node group of which the area is tiny. Then,a beacon node optimization is followed to eliminate the beacon nodes which are approximately in a line. Besides,the Genetic Chaos Particle Swarm Optimization algorithm was proposed based on the particle swarm optimization algorithm which com￣bine with genetic algorithms and chaos. Finally,the improved particle swarm optimization was used to correct the lo￣cation of DV￣Hop algorithm. The results from simulation show that the proposed improved algorithm has better loca￣ting performance in positioning accuracy than the traditional DV￣Hop algorithm in the same network environment. Therefore,the location of leakage can be monitored more accurately in the coal mine.关键词
