基于优化RSSI精度的WSN加权质心定位算法
RSSI accuracy WSNs based on optimized weighted centroid localization algorithm
摘要
Abstract
To weaken the received signal strength indication error of wireless sensor network node positioning accuracy, this paper proposes a weighted centroid localization algorithm to optimize the received signal strength indicator ranging precision. The algorithm is based on the Received Signal Strength Indicator(RSSI)and the Link Quality Indicator(LQI) in the fluctuation of the fading fluctuation curves at different distances. It uses the method of piecewise ranging accuracy optimization RSSI, then the optimized distance is valued as the weight factor weighted centroid algorithm to locate the node, so it improves the positioning accuracy. Simulation results show the validity of the optimization algorithm.关键词
