Overview of Localiation Techniques in WSN

Abstract

The present paper offers a comprehensive survey of localization methodologies employed in the context of wireless sensor networks (WSN). The process of localization plays a crucial role in Wireless Sensor Networks (WSNs) by providing the means to ascertain the spatial coordinates of sensor nodes, thereby enabling the deployment of diverse applications. Localization techniques can be categorised into four main types: range-based, range-free, hybrid, and machine learning-based techniques. Every method possesses its own set of merits and demerits, and the selection of a particular technique is contingent upon the precise demands of the given application.

The present review article conducts a comparative analysis of various localization techniques, evaluating their efficacy with respect to precision, expenses, and intricacy. Range-based methodologies provide a superior level of precision, however, they may necessitate supplementary hardware and are susceptible to signal interferences.

The study's importance lies in its provision of a comprehensive resource for researchers and practitioners engaged in the field of Wireless Sensor Networks (WSNs). It offers valuable insights into the various localization techniques and their applications. Comprehending the various localization methodologies employed in Wireless Sensor Networks (WSNs) is imperative for devising and executing proficient and potent WSNs. The present review article aims to provide valuable insights to both researchers and practitioners in order to facilitate informed decision-making regarding the selection of an appropriate localization technique for their respective applications.
