Target Detection, Localization, and Tracking in Wireless Sensor Networks

Abstract

This chapter will investigate target detection approaches, sensor node localization algorithms, and target tracking schemes in wireless sensor network (WSN). WSN is a self-organized distributed network composed of a large quantity of small, inexpensive sensor nodes. They are employed to capture information of the target, which is similar to humans’ sense of hearing, sight, smell, and touch. The integration of a plurality of homogeneous or heterogeneous sensors will result in more accurate target detection, node localization, and target tracking than that of a single sensor, and thus WSN plays an important role in military, environment, medical, and industrial fields.
