Book reviews: Cisco mobile IP configuration, troubleshooting, and management

Mobility in communication has become a reality - or has it? While mobile voice communication is a commodity today, this is far from true for data communication. Although wireless Internet access with smart phones, PDAs, and even laptops (at popular hot spots) has spread widely, this doesn't create true mobility for end users. True mobility requires more than a wireless connection wherever and whenever needed. Not only must the physical and data layers support handovers and roaming between cells and various types of wireless networks, but networking protocols must support moves between subnets and networks seamlessly without losing the connection. These protocols must also support the running applications without hiccups. This will mean the real convergence of desktop computing and cellular communications. In Mobile IP Technology and Applications, Stefan Raab and Madhavi W. Chandra clearly define mobility and its requirements. They explain the mobile Internet protocol in detail to the level of message flows.
