To affirm the validity of mobile host' cache content, servers periodically broadcast cache invalidation reports that contain information of data that has been updated. However, as mobile hosts may operate in sleeping mode (disconnected mode), it is possible that some reports may be missed and the clients are forced to discard the entire cache content. In this paper, we present a cache invalidation scheme base on mobile agent in mobile computing environments, which can manage consistency between mobile hosts and servers, to avoid losing cache invalidation reports.展开更多
