A Cost Effective Cache Consistency Method for Mobile Clients in Wireless Environment

When a mobile client disconnects for a prolonged time which exceeds the window size of the server’s invalidation reports , the mobile client’s cache is discarded even if most of data are still valid. In this paper, we propose an efficient cache consistency method called CCI(Cost-based Cache Invalidation) for mobile clients, which takes into account not only the disconnection time but also the update frequencies at a server.
