In our increasingly mobile world the ability to accessinformation on demand at any time and place can satisfy people'sinformation needs as well as confer on them a competitive advantage.The emergence of battery-operated, low-cost and portable computerssuch as palmtops and PDAs, coupled with the availability andexploitation of wireless networks, have made possible the potentialfor ubiquitous computing. Through the wireless networks, portableequipments will become an integrated part of existing distributedcomputing environments, and mobile users can have access to datastored at information servers located at the static portion of thenetwork even while they are on the move.Traditionally, information is retrieved following a request-responsemodel. However, this model is no longer adequate in a wirelesscomputing environment. First, the wireless channel is unreliable andthe bandwidth is low compared to the wired counterpart. Second, theenvironment is essentially asymmetric with a large number of mobileusers accessing a small number of servers. Third, battery-operatedportable devices can typically operate only for a short time becauseof the short battery lifespan. Thus, clients are expected to bedisconnected most of the time. To overcome these limitations, there has been a proliferation ofresearch efforts on designing data delivery mechanisms to supportwireless computing more effectively. Data Dissemination inWireless Computing Environments focuses on such mechanisms.The purpose is to provide a thorough and comprehensive review ofrecent advances on energy-efficient data delivery protocols, efficientwireless channel bandwidth utilization, reliable broadcasting andcache invalidation strategies for clients with long disconnectiontime. Besides surveying existing methods, this book also compares andevaluates some of the more promising schemes.
