RSSI-based positioning of wireless sensor network technology

Node localization plays a critical role in wireless sensor Network (WSN) and the information about node location is indispensable to many applications of WSN.This paper analyzes the wireless sensor network node positioning algorithm and the principle of classification,and will focus on analyzing the signal strength based ranging method (RSSI) of wireless location technology,put forward a theoretical value of the signal intensity values and experience of the positioning of the integration method.
