Abstract
Based on Received Signal Strength Indicator(RSSI),a modified weighted centroid localization algorithm is presented.Different from the former method,the sum of the reciprocal of each measured distance will be taken as the weight,instead of the reciprocal of sum.We also introduce a modified coefficient,which reduces the phenomenon of information drown,and the precision of localization is improved.The simulation result shows that the modified weighted centroid localization algorithm can provide an extra maximum precision gain of 17.83 %,compared with the former method.
