Indoor positioning systems have become very popular in recent years as asset and indoor tracking. In order to provide location information for indoor applications and context-aware computing, a lot of research is being done since last decade for development of real-time Indoor location system. This paper provides an overview of developing an Application based on tracking User Info and Location. The application will communicate with the Wifi - Infrared Adapter using Wifi which in turns communicate with sensors by Infrared and use the information to locate the smart phones in indoors. The sensors will sense these signals and triangulate the smart phone using trilateration algorithm. Then the required destination will be given onto the smart phone and the path to the destination will be calculated by the PIR Sensor by using Spanning Tree Algorithm.
