Abstract
We propose an update algorithm for Wi-Fi location fingerprint database will not occur the location fingerprint outdate situation when Wi-Fi environment in location area changes.This algorithm uses feedback data from users and takes APs adding and revocation detection issue in circumstance of AP signal unstable into account,eliminates the impact of temporary AP such as mobile phone hotpot on traditional update methods.Finally,this algorithm accelerates the location fingerprint database’s update by detecting the RSS changes caused by AP location moving.Experimental results show that in actual environment this algorithm is superior to the traditional update algorithms on update efficiency of fingerprint database.关键词
