Techniques of Node Localization in WirelessSensor Networks: A Review

Wireless sensor networks (WSNs) are widely used in many environments and adverse terrains. The common problem in the wireless sensor network technology is localization problem. Most of the applications, the network collects the data without location information which is not very useful. Location information plays a vital role in both networking and in other domains of wireless sensor network. In this paper, review has been done on the localization algorithms and different taxonomy based on basic features. As wireless sensor networks are becoming an emerging technology, it is being used in many applications. We have also reviewed the important and fundamental factors which can validate the performance of node localization techniques.
