摘要: Location-Based Services Handbook: Applications, Technologies, and Security is a comprehensive reference containing all aspects of essential technical information on location-based services (LBS) technology. With broad coverage ranging from basic concepts to research-grade material, it presents much-needed overview technologies for positioning localizing, including range- proximity-based localization methods, environment-based location estimation methods. Featuring valuable contributions field experts around the world, this book addresses existing future directions LBS technology, exploring how can be used optimize resource allocation improve cooperation in wireless networks. It self-contained, that presents: A detailed description technology Coverage privacy protection procedure cellular networksand its shortcomings An assessment threats presented when divulged unauthorized parties Important IP Multimedia Subsystem IMS-based presence service proposals The demand navigation predicted rise by combined annual growth rate more than 104% between 2008 2012, many these applications require efficient highly scalable system architecture support dissemination location-dependent resources large growing number mobile users. This offers tools aid determining optimal distance measurement given situation assessing factors complexity, accuracy, environment. provides an extensive survey literature proposes novel, widely applicable, solution. Organized into three major sectionsapplications, technologies, securitythis material fully covers various impact they will have future.
