Broadcast-Based Data Access in Wireless Environments
Broadcast is one of the most suitable forms of information dissemination over wireless networks. It is particularly attractive for resource limited mobile clients in asymmetric communications. To support faster access to information and conserve battery power of mobile clients, a number of indexing schemes have been proposed in recent years. In this paper, we report on our extensive study of some of the most representative indexing schemes. We present a novel adaptive testbed for evaluating wireless data access methods. A comprehensive analytical study of the sample indexing schemes is also presented. Exhaustive simulations of these indexing schemes have been conducted. As a result, selection criteria for the suitability of the indexing schemes for different applications are proposed.
