An Intelligent Localization System Based on RSSI Ranging Technique for WSN

An intelligent localization system based on RSSI for WSN is proposed. A RSSI( Signal Strength Indicator) model is established based on the study of RSSI theoretical model, and DV-Distance algorithm is improved by adding in weighted factors, which is completed on TinyOS. It is proved by practical experiment that the improved DV-Distance has the advantage of precision and stabilization than the standard DV-Distance, so it is appropriate to apply to wireless sensor networks.
