Description	Journal: Journal of Physics: Conference Series Localization of nodes is the key technology for application of wireless sensor network. The positioning accuracy of centroid localization algorithm completely depends on the size and the distribution density of anchor nodes. Anchor nodes are small and the density of anchor nodes are distributed randomly in actual application, so the positioning accuracy of centroid localization algorithm is relatively low. In order to improve the accuracy of nodes, a method which is centroid localization algorithm of wireless sensor network is proposed based on received signal strength indicator. In the algorithm, firstly, point-to-point signal intensity is computed by RSSI and converts its inverse distance as the centroid algorithm. Then the weights of centroid localization algorithm are used for calculating coordinates of the unknown node. Through the simulation algorithm for testing and analysis, the simulation results show that, compared with the traditional algorithm, the positioning error of the centroid localization algorithm is obviously reduced and the node location accuracy is improved. It is an effective localization algorithm for application of wireless sensor networks.
