In our increasingly mobile world the ability to access

information on demand at any time and place can satisfy people's

information needs as well as confer on them a competitive advantage.

The emergence of battery-operated, low-cost and portable computers

such as palmtops and PDAs, coupled with the availability and

exploitation of wireless networks, have made possible the potential

for ubiquitous computing. Through the wireless networks, portable

equipments will become an integrated part of existing distributed

computing environments, and mobile users can have access to data

stored at information servers located at the static portion of the

network even while they are on the move.

Traditionally, information is retrieved following a request-response

model. However, this model is no longer adequate in a wireless

computing environment. First, the wireless channel is unreliable and

the bandwidth is low compared to the wired counterpart. Second, the

environment is essentially asymmetric with a large number of mobile

users accessing a small number of servers. Third, battery-operated

portable devices can typically operate only for a short time because

of the short battery lifespan. Thus, clients are expected to be

disconnected most of the time.

To overcome these limitations, there has been a proliferation of

research efforts on designing data delivery mechanisms to support

wireless computing more effectively. Data Dissemination in

Wireless Computing Environments focuses on such mechanisms.

The purpose is to provide a thorough and comprehensive review of

recent advances on energy-efficient data delivery protocols, efficient

wireless channel bandwidth utilization, reliable broadcasting and

cache invalidation strategies for clients with long disconnection

time. Besides surveying existing methods, this book also compares and

evaluates some of the more promising schemes.
