REAL-TIME POSITION TRACING METHOD AND SYSTEM FOR MOBILE DEVICE

摘要

PURPOSE: A method and a system for real-time position tracing a mobile device is provided to reduce computing power using a Bayesian Probabilistic Access to which a compensation algorithm is applied. CONSTITUTION: A received signal strength indicator(RSSI) receiving component(1) transfers a received RSSI from a client to a location tracing component(3). A calibration component(2) calculates or stores the average value and the standard deviation of the RSSI. The location tracing component traces the location of the client. A position history data component(4) accumulates and manages the location history information in a measurement target region.
