Ground Based Wireless Positioning provides an in-depth treatment of non-GPS based wireless positioning techniques, with a balance between theory and engineering practice. The book presents the architecture, design and testing of a variety of wireless positioning systems based on the time-of-arrival, signal strength, and angle-of-arrival measurements. These techniques are essential for developing accurate wireless positioning systems which can operate reliably in both indoor and outdoor environments where the Global Positioning System (GPS) proves to be inadequate. The book covers a wide range of issues including radio propagation, parameter identification, statistical signal processing, optimization, and localization in large and multi-hop networks. A comprehensive study on the state-of-the-art techniques and methodologies in wireless positioning and tracking is provided, including anchor-based and anchor-free localisation in wireless sensor networks (WSN). The authors address real world issues such as multipath, non-line-of-sight (NLOS) propagation, accuracy limitations and measurement errors. Presenting the latest advances in the field, Ground Based Wireless Positioning is one of the first books to cover non-GPS based technologies for wireless positioning. It serves as an indispensable reference for researchers and engineers specialising in the fields of localization and tracking, and wireless sensor networks. . Provides a comprehensive treatment of methodologies and algorithms for positioning and tracking. Includes practical issues and case studies in designing real wireless positioning systems. Explains non-line-of-sight (NLOS) radio propagation and NLOS mitigation techniques. Balances solid theory with engineering practice of non-GPS wireless systems.

This book extends current understandings of the effects of using locative social media on spatiality, the experience of time and identity. This is a pertinent and timely topic given the increase in opportunities people now have to explicitly and implicitly share their location through digital and mobile technologies. There is a growing body of research on locative media, much of this literature has concentrated on spatial issues. Research here has explored how locative media and location-based social media (LBSN) are used to communicate and coordinate social interactions in public space, affecting how people approach their surroundings, turning ordinary life ?into a game?, and altering how mobile media is involved in understanding the world. This book offers a critical analysis of the effect of usage of locative social media on identity through an engagement with the current literature on spatiality, a novel critical investigation of the temporal effects of LBSN use and a view of identity as influenced by the spatio-temporal effects of interacting with place through LBSN. Drawing on phenomenology, post-phenomenology and critical theory on social and locative media, alongside established sociological frameworks for approaching spatiality and the city, it presents a comprehensive account of the effects of LBSN and locative media use.

From Guy Debord in the early 1950s to Richard Long, Janet Cardiff, and Esther Polak more recently, contemporary artists have returned again and again to the walking motif. Today, the convergence of global networks, online databases, and new tools for mobile mapping coincides with a resurgence of interest in walking as an art form. In Walking and Mapping, Karen O'Rourke explores a series of walking/mapping projects by contemporary artists. She offers close readings of these projects -- many of which she was able to experience firsthand -- and situates them in relation to landmark works from the past half-century. Together, they form a new entity, a dynamic whole greater than the sum of its parts. By alternating close study of selected projects with a broader view of their place in a bigger picture, Walking and Mapping itself maps a complex phenomenon.
