摘要：

As a new information acquisition and processing technology, wireless sensor networks can achieve tasks with complex large-scale monitoring and tracking in wide range of applications, but the localization for node itself is the basis of most applications. APIT is a major localization algorithm of ranged free algorithms, but the algorithm has the problems of big localization errors and low coverage rate, it also has high dependence on the number of anchor nodes. In order to overcome these disadvantages, this paper propose a mixed localization algorithm based on RSSI and APIT with fitness analysis and optimization, According to the experiment and simulation, the new algorithm has smaller localization errors, higher coverage rate, and improves the overall stability of nodes' localization.
