Target localization and tracking problems in WSNs have received considerable attention recently, driven by the requirement to achieve high localization accuracy, with the minimum cost possible. In WSN based tracking applications, it is critical to know the current location of any sensor node with the minimum energy consumed. This paper focuses on the energy consumption issue in terms of communication between nodes whenever the localization information is transmitted to a sink node. Tracking through WSNs can be categorized into centralized and decentralized systems.
