Localization Techniques in WSN: A Review
Journal Title: Scholars Journal of Engineering and Technology - Year 2014, Vol 2, Issue 2
Abstract
Wireless Sensor Network (WSN) is a kind of wireless network, which is composed of groups of very small devices known as ‘Sensor Nodes’. It is one of the fastest evolving fields. Applications of WSN comprise of search, disaster relief, remote environmental monitoring, target tracking etc. In all such applications, data gathered by the network is not useful, without location information. As nodes location is required to report the origin of event, about which the data is gathered. Node localization is highly important, for large sensor networks where users desire, to know about the exact location of the nodes to know the event location. This paper reviews different localization techniques, used for nodes location discovery in WSN and presents their parametric comparison in tabular form. This comparison is useful for better understanding of existing techniques and for the development of other novel technique. Keywords: Wireless Sensor Network (WSN), approaches, sensor nodes
