A Taxonomy of Localization Schemes for Wireless Sensor Networks.

Abstract

Knowledge of nodes’ locations is an essential requirement for many applications. This paper surveys the current state of the art for localization schemes in sensor networks. We present a taxonomy of the localization schemes for sensor networks based on different features. We then describe how the current localization schemes for sensor networks map to these different features. We believe that this paper serves as an introduction for researchers interested in the area of localization schemes for sensor networks as well as in evaluating the characteristics of a location system needed by a particular application or the suitability of an existing location system for
