In Wireless Sensor Networks (WSNs), node's locations play a critical role in many applications. Having a GPS receiver on every sensor node is costly. In this paper, the authors propose an adaptive mobile anchor localization algorithm based on ant colony optimization, firstly, some virtual anchor nodes are distributed in the area, second, ant colony was used which has the maximum of transition probabilities to obtain the optimal path, last, the centroid-weighted localization algorithm was proposed to locate the position of unknown nodes.
