| Summary: | 碩士 === 國立交通大學 === 資訊工程系 === 91 === In wireless data transmission,
the capacity of wireless link
is typically limited. Since many applications exhibit temporal locality for
data access, the cache mechanism can be built in a wireless terminal
to effectively reduce the data access time.
This thesis studies the cache performance of the wireless terminal by
considering a business card application. We investigate
the least recently used replacement policy and two strongly consistent
data access algorithms called poll-each-read and callback.
An analytic model is proposed to derive the effective
hit ratio of data access,
which is used to validate against simulation experiments.
Our study reports how the data access rate and the data update distribution
affect the cache performance in a wireless terminal.
