A Novel Sensor Web System for Tracking and Surveillance

Current sensor network technology for detection and tracking are focused solely in terms of static networks and suffers from device specific inadequacies such as lack of coverage, power and fault tolerance. Failing nodes result in coverage loss or breakage in connectivity and hence there is a pressing need for a robust system. In this work a unique sensor network is fielded that uses multiple frequencies and transmit powers to improve coverage. A novel approach to track a sensor node is also presented. Simulation data is compared to experimental results for validation.
