Title   Research on Centroid Localization Algorithm for Wireless Sensor Networks
Abstract
In WSN, node localization in wireless sensor network is one of its most basic functions, only to have the location information of the monitoring data is the research and application value, so the positioning of the sensor nodes in the sensor network application is very critical.
Firstly the wireless sensor network, and the existing wireless sensor network localization algorithm were introduced, taking into account the location of cost and other factors, this paper explained the centroid localization algorithm, but the centroid localization algorithm, positioning accuracy is not high, so this paper introduces weighted centroid localization algorithm based on signal strength. Through MATLAB, the two algorithms are simulated, and the feasibility of the two algorithms is determined by simulation.. Based on MATLAB, the two algorithms are compared and the results are concluded. The weighted centroid localization algorithm has higher accuracy than the centroid localization algorithm.
