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.
