摘要

This paper considers the localization algorithms of wireless sensors networks. Among these algorithms, Convex is an algorithm that costs very low while its accuracy is also low, because it uses the center of the polygons as the localization result. Instead of localizating from those invalid positions contained in the algorithm, we propose an improved Convex localization algorithm named Convex-CIS (Circle In Shadow). To achieve higher localization accuracy, Convex-CIS uses the inscribed circle of the polygons so that it can exclude those invalid position while maintaining the low power consumption. Moreover, the simulation results show that Convex-CIS can improve the accuracy of localizating algorithm for those unknown nodes.
