An Improved Localization Algorithm in Wireless Sensor Networks

Abstract:

Min-Max localization algorithm is usually used to acquire the position of a sensor node in wireless sensor networks by the reason of its simpleness and low complexity. However, Min-Max algorithm provides a coarse position estimation. In order to increase its accuracy, an Extended Min-Max (E-Min-Max) algorithm has been proposed. In this paper we focus on this algorithm and propose an improved E-Min-Max algorithm to enhance its accuracy further. Simulations show that the improved E-Min-Max algorithm outperforms its original version in localization.
