A Comparison of Modern Localization Techniques in Wireless Sensor Networks (WSNs)

Wireless Sensor Networks (WSNs) has acquired a well-known significance in the domain of sensor networks due to the advancement in past decade by the introduction of Internet of Things (IoT). WSNs comprises of sensor and the basic purpose of sensor is to collect, analyze and transmit the information to the target node/sensor. Therefore, it is necessary to identify target area of sensor node. In WSNs, it is achieved through applications of various algorithms and techniques known as localization techniques. These localization approaches help in determining the actual geographical location of sensor nodes. The main focus of this paper is to provide a comparative study of different localization techniques used in WSNs. This paper significantly helps the students, researchers and practitioners in this domain for selecting right localization technique as per the given WSNs requirements.
