Abstract: Since the positions of events or nodes are the most important part of monitoring information from sensor nodes, how to obtain the accurate localization has become the focus of the attention. Based on Weighted Centroid method, this paper presents a new RSSI-verify based localization algorithm for wireless sensor network which takes the known distance and its corresponding RSSI between the fixed nodes into account and amends the weights of the fixed nodes, thus improving the localization accuracy of the mobile nodes. The experimental results show that the proposed method outperforms Weighted Centroid method under the same environment. Especially, the former decreases the average localization error by about 25% compared with the latter.
