Evolution of Target Localization in Wireless Sensor Network (WSN): A Review
share
Wireless Sensor Network holds a pivotal position and gained a lot of attention from researchers in recent years. Sensor nodes have been used in vast applications such as environment monitoring, security purpose applications, and target tracking. This latter comprises of detection and monitoring of the target movement. In this paper, we explore in detail well-known target tracking techniques. The existing techniques are evaluated using metrics such as network topology, target recovery, energy efficiency, and security. We also discuss some of the challenges that affect the performance of tracking schemes. Furthermore, a thorough analysis is performed on existing techniques and future directions are explored.
