Object Organization on a Single Broadcast Channel in the Mobile Computing Environment [chapter]

Y. C. Chehadeh, A. R. Hurson, M. Kavehrad
1999 Mobile Computing Environments for Multimedia Systems  
Learning from our past experiences in objects organization on conventional storage mediums (disks), we propose schemes for organizing objects along a single broadcast air channel.  ...  In this work, we concentrate on the effects of the mobile-computing environment on query processing in multidatabases.  ...  The data is transmitted to the mobile support stations (MSSs). A MSS broadcasts the data on a certain air channel and is responsible for servicing the mobile hosts (MHs) within its cell.  ...
