Zigbee based indoor location tracking and monitoring system

Abstract

Indoor positioning systems (IPS) are used to locate objects or moving persons in indoor environments based on sensors and different wireless communication technologies. Nowadays IPS are very attractive because it finds applications in several areas. GPS and cellular systems have a very wide range of applications in location tracking and monitoring, but it gives poor performance in indoor environment. This project presents a low- cost approach for location tracking and monitoring system using ZigBee Technology in indoor environment. ZigBee is a low cost, low power wireless communication technology. This is an ideal communication technology for indoor positioning in terms of its unique characteristics. System uses location fingerprinting method for position estimation. Fingerprinting is an effective technique for indoor localization. In this method the location-related fingerprints will be formed by collecting signals from different access points. when it receives an instruction to locate a position of a person or object, it will execute RSSI based location monitoring algorithm to obtain the matched record within the database. After that it will return the corresponding locations to the user. The system makes use of IoT Technology to view the location of a specific person in indoor environment through a webpage. System consists of ATMEGA2560 microcontroller, ZigBee modules, ATMEGA328 microcontroller, Raspberry pi 3, LCD, laptop/PC, etc.
