Of all Britain's great archaeological monuments the Iron Age hillforts have arguably had the most profound impact on the landscape, if only because there are so many; yet we know very little about them. Were they recognised as being something special by those who created them or is the 'hillfort' purely an archaeologists' 'construct'? How were they constructed, who lived in them and to what uses were they put? This book, which is richly illustrated with photography of sites throughout England and Wales, addresses these and many other questions. After discussing the difficult issue of definition and the great excavations on which our knowledge is based, Ian Brown investigates in turn hillforts' origins, their architecture, and the role they played in Iron Age society. He also discusses the latest theories about their location, social significance and chronology. The book provides a valuable synthesis of the rich vein of research carried out in Britain on hillforts over the last thirty years. Hillforts' great variability poses many problems, and this book should help guide both the specialist and non-specialist alike though the complex literature. Furthermore, it has an important conservation objective. Land use in the modern era has not been kind to these monuments, with a significant number either disfigured or lost. Public consciousness of their importance needs raising if their management is to be improved and their future assured.

Local Positioning Systems: LBS Applications and Services explores the possible approaches and technologies to location problems including people and asset tracking, mobile resource management, public safety, and handset location-based services. The book examines several indoor positioning systems, providing detailed case studies of existing applications and their requirements, and shows how to set them up. Other chapters are dedicated to position computation algorithms using different signal metrics and determination methods, 2D/3D indoor map data and location models, indoor navigation, system components and how they work, privacy, deployment issues, and standards. In detail, the book explains the steps for deploying a location-enabled network, including doing a site-survey, creating a positioning model and floor maps, and access point placement and configuration. Also presented is a classification for network-based and ad-hoc positioning systems, and a framework for developing indoor LBS services. This comprehensive guide will be invaluable to students and lecturers in the area of wireless computing. It will also be an enabling resource to developers and researchers seeking to expand their knowledge in this field.
