The first few chapters present the concepts of mobile computing and mobile communication in equal measure, including 2G, 2.5G, 3G, 3G+, and 4G communication systems, mobile satellite communication networks, mobile IP, mobile TCP and digital audio-video broadcasting, and mobile TV. The subsequent chapters provide a systematic explanation of mobile computing as a discipline in itself. The book provides an in-depth coverage of mobile systems and devices, mobile operating systems used for application development, mobile databases, client-server computing agents, application servers, security protocols, mobile Internet, and ad-hoc and sensor networks.
