Sensor localization has become an essential requirement for realistic applications over Wireless Sensor Networks (WSNs). As such localization scheme designed for mobile sensor networks is necessary. Here the objective is to design a localization scheme to improve the localization accuracy by using localization scheme Improved Monte -Carlo Localization (IMCL). In this method, all sensor nodes are mobile, normal node collects the locations of its one-hop and two-hop anchor nodes via message exchange, and constructs a new possible location set in each time slot where the normal node may locate.
