Localization Algorithm for Wireless Sensor Networks Based on RSSI
-
Abstract
We propose a least square method to obtain environmental parameters and choose appropriate Gauss model for processing the measured RSSI data,then using the improved trilateration localization algorithm to locate the target node,Experimental results show that the algorithm reduces positioning influenced by environmental factors,while have higher accurcy than traditional RSSI location algorithm,can be widely used ZigBee positioning system.
