Design and Simulation of Indoor Position System Based on PDR and Least Square RSSI Estimation

In this paper, we at first proposed a Least Square RSSI Estimation algorithm for the indoor wireless position. Next, a wireless indoor position system is designed based on the proposed algorithm and the PDR (Pedestrian Dead Reckoning) is used to correct the deviation of RSSI indoor position algorithm in this system. The simulations showed that the proposed method has a 34% accuracy improvement over systems based on the traditional RSSI indoor position algorithm. The proposed system provides a new algorithm for the indoor wireless position.
