A COMPUTER IMPLEMENTED SYSTEM AND METHOD FOR WI-FI BASED INDOOR LOCALIZATION

摘要

A computer implemented system and method for Wi-Fi based indoor localization is disclosed. The system includes a server having preconfigured information regarding an indoor environment. A user device while moving across the indoor environment, installed with Wi-Fi access points, captures data point values. The data point values are a group of signal strength indicators called as Received Signal Strength Indicators (RSSI). The user device transmits the captured data point values to the server at regular intervals. The server processes the data point values and prepares a decision tree for determining the zone of user location in the indoor environment. The decision tree is kept updated by the server as it receives new set of data point values. The updated decision tree is transmitted to the user device. The user device records a new data point value and determines its location by searching for the value in the decision tree.
