Query: Evolution of Target Localization in Wireless Sensor Network (WSN): A
  Review   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.
