Understanding the cornerstone of an efficient communications network Mobility is defining the future of computing, and in a resource-limited wireless environment, interoperability and performance present a major challenge that has baffled researchers and engineers for years. Now, Wireless Internet and Mobile Computing is the first book to tackle this issue with a thorough examination of how these distinctive technologies can work together, through various adaptation methods, to maintain an effective communications network. The authors' "bottom up" approach cuts through all protocol stacks in a communication system to describe how application needs affect the underlying physical layer and network layer designs, and explains how the various devices in a large networking system can communicate with each other.
Divided into six parts, the book explores:
Essentials of Wireless Communications
Cellular Wireless Technologies
Short-Range Wireless Technologies
Protocol Adaptations for Wireless Networking
Wireless Resources Management
Mobile Computing Application Issues
Throughout the book, practical, real-life case studies serve as motivating examples to help you gain an in-depth understanding of the technologies being discussed. Whether you're a student, researcher, or practitioner in the field, this is the only book that covers the scope and depth of this fundamental topic.
This book describes the technologies involved in all aspects of a large networking system and how the various devices can interact and communicate with each other. Using a bottom up approach the authors demonstrate how it is feasible, for instance, for a cellular device user to communicate, via the all-purpose TCP/IP protocols, with a wireless notebook computer user, traversing all the way through a base station in a cellular wireless network (e.g., GSM, CDMA), a public switched network (PSTN), the Internet, an intranet, a local area network (LAN), and a wireless LAN access point. The information bits, in travelling through this long path, are processed by numerous disparate communication technologies. The authors also describe the technologies involved in infrastructure less wireless networks.
