Abstract

Advances in computation and communication technologies allow users toaccess computer networks, using portable computing devices via a wirelessconnection, while mobile. Furthermore, multidatabases offer practical means ofmanaging information sharing from multiple preexisting heterogeneous databases. By superimposing the mobile computing environment ontothe multidatabase system, a new computing environment is attained.In this work, we concentrate on the effects of the mobile-computing environment on query processing in multidatabases. We show how broadcasting, as a possible solution, would respond to current challenges such as bandwidth and storage limitations. Organizing data objects along a single-dimension broadcastchannel should follow the semantic links assumed within the multiple-dimensionobjects‘ structure. Learning from our past experiences in objects organizationon conventional storage mediums (disks), we propose schemes for organizingobjects along a single broadcast air channel. The proposed schemes are simulated and analyzed.
