Abstract

Toward the problem of low node localization accuracy in wireless sensor networks, this paper analyzes the centroid localization and proposes a weighted centroid localization algorithm based on improved RSSI ranging. This algorithm takes both the distance and RSSI between beacon nodes into consideration, corrects both the distance between beacon nodes and the signal strength information and selects the reciprocal of the distance as the weight of the algorithm. The simulation result shows, compared with the traditional centroid localization algorithm this algorithm has higher localization accuracy.
