A localization method developed for mobile sensor networks is necessary. In this paper, a localization method is presented by many sensor nodes in a mobile sensor network. The sensor node is classified into normal node and anchor. Normal node doesn’t know its geographic location, but it obtains location information from Anchors to compute estimate location. However, an anchor knows its location information at each time unit. Here, we propose a method of power-aware localization to improve the localization accuracy. Simulation results show that the localization accuracy in our method is better than that of previous method in different moving speeds.
