Devotees Tracking Using GPS and ISP
S. Sudha, L. Gowthami · i-manager’s Journal on Wireless Communication Networks · 2013
Every day, lakhs of devotees gather in Tirupathi. Tracking the movement of such a large number of people is crucial to the devotees them-selves and the authorities managing the whole event. This paper reports a real-time devotee tracking system that has been designed and implemented. The system relies on a dedicated delay-tolerant Wireless Sensor Network (WSN). This WSN is interfaced to the Internet through gateway(s) available from an Internet Service Provider (ISP) . Energy efficiency, robustness, and reliability are key factors in the design of the system. Each devotee is given a mobile sensor unit which includes a GPS chip, a microcontroller, and antennas. A network of fixed units is installed in the Holy shrine for receiving and forwarding data. Periodically, each mobile unit sends its User Identification (UID), latitude, longitude, and a time stamp. A central server maps the latitude and longitude information on a Geographical Information System (GIS). The developed system can be used to track a specific or a group of devotees.
