In mobile computing caching plays a vital role owing to its ability to alleviate the performance and availability limitations of weakly-connected and disconnected operations. An efficient way to reduce query delay, save bandwidth and improve system performance is to cache the frequently accessed data objects at the local buffer of a mobile. Owing to the disconnection and mobility of the mobile clients, classical cache management strategies may be inappropriate for mobile environments. Generally, cache placement, cache discovery, cache consistency and cache replacement techniques constitute cache management in mobile environment. In this paper, we design a distributed cache management architecture which includes all the above techniques. The architecture also includes a location update procedure for a moving mobile client. The simulation results illustrate that our proposed architecture achieves lower latency and packet loss, reduced network bandwidth consumption, and reduced data server workload.
