A robot-walk-based collaborative algorithm for target tracking in ad hoc sensor networks

Recent advances in processor, memory and radio technology have enabled cheap nodes capable of sensing, communication and processing. Networks of distributed micro sensors are rapidly emerging as a feasible solution to a wide range of data gathering applications. This work develops a framework for using a wireless ad hoc network of distributed sensors for detection and tracking of moving objects. Each sensor can monitor a wide variety of ambient conditions in other to detect the presence of target. We first propose algorithms which can lead a mobile sensor (or mobile sensors) to reach the exact position of the object which is not moving. We generalize this approach for target tracking using collaborative sensors.
