The localization of anchor-free wireless sensor network’s serious cumulative error leads to low positioning accuracy. To solve this problem, paper proposed a co-located method based on asynchronous change learning factor adaptive weights particle swarm optimization algorithm (SAAPSO) and Taylor algorithm. first phase is building relative coordinate system. second estimating the node’s initial position with SAAPSO using iterative calculate in obtain accurate result. In third stage, node precise coordinates takes part rest nodes. Simulation results show that: has smaller higher
