一种基于优化RSSI精度的加权质心定位算法
A WEIGHTED CENTROID LOCALIZATION ALGORITHM BASED ON OPTIMIZED RSSI PRECISION
摘要
Abstract
Aiming at the influence of the received signal strength error in wireless sensor networks,on the basis of using the ratio of signal strength as the weighting factor,a weighted centroid localization algorithm based on optimized signal strength precision is proposed.First,the algorithm modified the signal strength (RSSI) value.A weighted factor of each RSSI value was counted,and the original RSSI values were replaced with weighted RSSI values.Then,the sum of the reciprocal of the ratio of the modified signal strength was used as the weighting factor of the algorithm.The experimental results show that the localization accuracy of our algorithm is improved by 61.5％ ～87.3％ than that of the traditional centroid algorithm,and 32.7％ ～ 46.4％ higher than the RR-WCL algorithm.关键词
