An Improved Weighted Centroid Localization Algorithm in WSN

Abstract:

This paper presents a weighted centroid localization algorithm which based on the nearest beacon node. It utilizes Beacon nodes From the unknown node nearest to correct ranging error caused by RSSI distance, Increased unknown node capability which adapt neighboring nodes distributed environment. Improved the positioning accuracy,. Simulation results indicate that the Positioning accuracy of Improved Algorithm which is Proposed in this article has been significantly improved, the highest Enhanced can up to 30%.
