Abstract
In the mobile wireless computing environment of the future a large
number of users equipped with low powered palmtop machines will query databasesover the
wireless communication channels. Palmtop based units will often be
disconnected for prolonged periods of time due to the battery power
saving measures; palmtops will also frequently relocate between
different cells and connect to different data servers at different
times. Caching of frequently accessed data items will be an important
technique that will reduce contention on the narrow bandwidth wireless
channel. However, cache invalidation strategies will be severely
affected by the disconnection and mobility of the clients. The server
may no longer know which clients are currently residing under its cell
and which of them are currently on. We propose a taxonomy of
different cache invalidation strategies and study the impact of
client's disconnection times on their performance. We determine that
for the units which are often disconnected (sleepers) the best cache
invalidation strategy is based on signatures previously used for
efficient file comparison. On the other hand, for units which are
connected most of the time (workaholics), the best cache invalidation
strategy is based on the periodic broadcast of changed data items.
