Abstract
With the rapid development of wireless technology, indoor positioning using WiFi has become a hot spot in the current positioning field. At present, WiFi signals are ubiquitous, resulting in uneven AP deployment and redundancy, which affects positioning accuracy. In this paper, an AP selection algorithm based on information entropy and mutual information is proposed by analyzing the characteristics of AP signals to optimize the AP. Its positioning accuracy is significantly better than the other two AP selection algorithms.
