A Tracking System For Wireless Embedded Nodes Using Time-Of-Flight Ranging

Abstract

In this work we present the design, development and evaluation of a real-time target tracking system for wireless embedded nodes, capable of effectively tracking maneuvering targets. The proposed tracking system is designed to operate solely on range measurements obtained with the use of a two-way Time-of-Flight method without the need for additional hardware being incorporated in the nodes. Ultimately, the entire system is implemented on commercially available hardware and tested in an outdoor deployment. The main modules in this project are RF transducers, RF tags, PC and Microcontroller. The RF Transmitter is connected with each flight. In each node, RF ID sensors are connected. A client is connected with each node through microcontroller. When the flight reaches the node, the receiver receives the factors and sends to the microcontroller. The microcontroller sends the corresponding data to the Client through USART. Each client is connected through network. The difference in range from one node to another node gives the speed of the flight. The speed and timings are monitored and stored in the clients as well as server.
