From the Back Cover
The term "pervasive computing" describes a revolutionary dimension of personal computing which brings together mobile communications, ubiquitous embedded computer systems, consumer electronics and the power of the internet. Three main factors drive its growth: microelectronic technology, providing smaller devices and displays with lower energy consumption; communication technology, providing higher bandwidth and higher data transfer rates at lower cost; and ongoing international standardization efforts, without which the benefits of the technology can never be realized.
Written by a team of experts, Pervasive Computing: Technology and Architecture of Mobile Internet Applications provides both a theoretical overview and a practical guide to this emerging field. The first part of the book walks through the essential protocols, standards and architectures involved. The second part uses a continuous real-world example to present an end-to-end architecture for implementing pervasive computing applications.
Contents of Pervasive Computing include:
- Introduction to pervasive devices and their applications
- Overview of the key technologies and protocols
- Web application concepts
- WAP and beyond
- Voice Technology
- Server-side programming in Java
- Pervasive web application architecture
- Device-independent example application
- Accessing the example application via PC, PDA, WAP and voice
Pervasive Computing: Technology and Architecture of Mobile Internet Applications is the first book to offer an understanding of the scope and the implications of pervasive computing. As such it should be essential reading for IT managers, professionals, architects, consultants, developers, and students concerned with internet and web technologies.

and the example in the second half of the book showing how to write a concrete application in Java on a server to deliver content to a PDA, a WAP phone, a PC web browser, and to a voice device is very well done.
There are some things which are not clear - for example, why would someone give their PIN to an applet (12.1.2 pg. 316) which could then sign anything via the smart card! Another questions is
why is WAP so useful, if you have to test you application with each specific device and code around its behavior (13.2.1 pg. 338).
Although the back cover talks about "ubiquitous embedded computer systems, consumer electronics" other than pictures of IBM's web watch and some digital jewerly all of the devices seem to be assuumed to have considerable computing power (at least a complete Java environment). Perhaps this book is best read in conjunction with "The TINI Specification and Developer's Guide" by Don Loomis, which looks at things from the small device rather than the server point of view.
