Abstract
The sixth chapter, A pragmatic approach to cooperative positioning in wireless sensor networks, contributed by Albert Bel, Jose Lopez Vicario and Gonzalo Seco Granados from the Universitat Autonoma de Barcelona - UAB, Spain, is devoted to the theoretical framework behind localization techniques in wireless sensor networks. In recent years, location estimation in wireless sensor networks (WSN) has raised a lot of interest from researchers. In particular, much attention has been recently paid to cooperative positioning techniques as accurate positioning estimates can be obtained in networks with low complexity and low-cost terminals. The objective of this chapter is to provide a review on cooperative schemes for WSN. Among all of them, special emphasis is given to receive signal strength (RSS) based techniques as they provide suitable solutions for practical implementation. Since the accuracy of RSS methods depends on the suitability of the propagation models, cooperative localization algorithms that dynamically estimate the path loss exponent are also described. Besides, practical examples based on real WSN deployments are presented. © 2013 John Wiley & Sons, Ltd.
