Abstract—Node localization technology is one of the key technologies in wireless sensor network. The traditional three edge localization algorithm is analyzed, which exists in poor stability in practical issues in wireless sensor networks. In this paper the Min-Max wireless sensor network topology optimization localization algorithm based on RSSI is proposed. Through the fixed anchor node coordinates using pretreatment method of the RSSI values, the accuracy of distance calculation is improved to obtain more precise positioning. And experiments using actual sensor nodes verify the effectiveness of the algorithm.
