An Efficient Range-Based Localization Algorithm for Mobile Wireless Sensor Networks

摘要

Localization is one of the crucial issues in current mobile wireless sensor networks (MWSNs). And localization algorithms for MWSNs can be classified as range-based and range-free. In this paper, we propose an efficient range-based localization (RBL) algorithm for MWSNs. And our method is based on the MCL method. The RBL algorithm is divided into three phases: prediction, filtering and computation. In our method, the range information is used, and the localization accuracy is improved by utilizing the measurement information between nodes and the characteristics of moving nodes. Simulation results verify that compared with other known localization methods, the localization accuracy of RBL algorithm is largely improved.
