A Weighted Centroid Localization Algorithm for Wireless Sensor Networks

Abstract

Localization phase for sensor nodes is considered as the most important service for many applications of IoT. In the last decides, many localization algorithm have been presented to provide location of sensor nodes, but a limited number of these algorithms have been introduced to accurately estimate the location of sensor nodes in the Internet of Things (IoT). In this paper, we propose localization algorithms for sensor nodes in WSNs. The algorithms based on Centroid localization algorithm for Internet of Things. The Proposed algorithm is based on the new weighted formula to calculate the position of unknown nodes. Our presented algorithms guarantee that the nodes estimate their own position with a butter localization accuracy in comparison to the Centroid algorithm and DV-Hop in all considered scenarios. Moreover, the proposed simulation confirms that the introduced algorithms can significantly enhance the localization error and of algorithms in Wireless Sensor Networks.
