Due to the complexity of indoor wireless environment, indoor position is more difficult than other location technologies in wireless sensor network and how to improve accuracy of location is one of the key research problems. So a new hybrid algorithm based on RSSI (Received Signal Strength Indicator) is proposed. In this algorithm, a dynamic real-time method of solving path fading factor is introduced, which improves accuracy of RSSI ranging obviously; then a modified algorithm based on weighted centric algorithm is used, which improves accuracy of location estimation.
