Speedy and prompt access to information on the Internet is critical to maintaining quality of service (QoS) in a large number of applications. In this paper we propose an integrated caching scheme for mobile computing environments. Wireless links in mobile environments provide flexibility, but introduce low bandwidth and resource constraints. In the integrated cache, cached (traditional), prefetched, and push cached items compete with each other for cache space. The weight of an item in the cache is determined by several network specific and user defined parameters. A dynamic programming technique is employed to determine the optimal set of cache items. Such an optimized cache increases hit ratio and thereby reduces the strain on the wireless link and enhances QoS provisioning.
