In order to assist mobile clients in maintaining the consistency of their caches, a number of cache invalidation techniques have been proposed [1-14].
To overcome the limitations of existing cache invalidation strategies, this paper presents a synchronous stateful caching strategy where cache consistency is maintained by periodically broadcasting update reports (URs) and request reports (RRs).
Section 2 gives a brief review on some representative approaches on cache invalidation.
As a result, valid items could be falsely invalidated; that is, false invalidations set in.
In order to reduce false invalidations, a hierarchically structured, more detailed report has been proposed [Jing 97].
Clearly, this "half-update" scheme may not yield minimal false invalidations.
