商品描述
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 a much-needed overview of technologies for positioning and localizing, including range- and proximity-based localization methods, and environment-based location estimation methods. Featuring valuable contributions from field experts around the world, this book addresses existing and future directions of LBS technology, exploring how it can be used to optimize resource allocation and improve cooperation in wireless networks.
It is a self-contained, comprehensive resource that presents:
- A detailed description of the wireless location positioning technology used in LBS
- Coverage of the privacy and protection procedure for cellular networks―and its shortcomings
- An assessment of threats presented when location information is divulged to unauthorized parties
- Important IP Multimedia Subsystem and IMS-based presence service proposals
The demand for navigation services is predicted to rise by a combined annual growth rate of more than 104 percent between 2008 and 2012, and many of these applications require efficient and highly scalable system architecture and system services to support dissemination of location-dependent resources and information to a large and growing number of mobile users.
This book offers tools to aid in determining the optimal distance measurement system for a given situation by assessing factors including complexity, accuracy, and environment. It provides an extensive survey of existing literature and proposes a novel, widely applicable, and highly scalable architecture solution. Organized into three major sections―applications, technologies, and security―this material fully covers various location-based applications and the impact they will have on the future.
商品描述(中文翻譯)
《基於位置的服務手冊：應用、技術與安全》是一部全面的參考資料，涵蓋了基於位置的服務（LBS）技術的所有基本技術資訊。該書的內容範圍廣泛，從基本概念到研究級材料，提供了對定位和本地化技術的必要概述，包括基於範圍和接近度的本地化方法，以及基於環境的定位估算方法。書中包含來自全球領域專家的寶貴貢獻，探討了LBS技術的現狀和未來方向，並研究了如何利用這些技術來優化資源配置和改善無線網絡中的合作。
這是一本自成體系的綜合資源，提供了：
- 對LBS中使用的無線位置定位技術的詳細描述
- 對行動網絡隱私和保護程序的覆蓋——及其不足之處
- 當位置資訊洩露給未經授權方時所帶來的威脅評估
- 重要的IP多媒體子系統和基於IMS的存在服務提案
預測在2008年至2012年間，導航服務的需求將以超過104%的年增長率上升，許多這些應用需要高效且高度可擴展的系統架構和系統服務，以支持向大量不斷增長的行動用戶傳播依賴位置的資源和資訊。
本書提供工具，幫助評估包括複雜性、準確性和環境等因素，以確定特定情況下的最佳距離測量系統。它提供了現有文獻的廣泛調查，並提出了一種新穎、廣泛適用且高度可擴展的架構解決方案。內容分為三個主要部分——應用、技術和安全——全面涵蓋各種基於位置的應用及其對未來的影響。
