Intelligent Cache Capacity Allocation and Relocation Schemes in a Mobile Proxy

In a mobile environment, since a mobile user is able to freely move around these cells, an inter service area handoff occurs when a user moves from the service area of one proxy to that of another. Some cache misses may be incurred by inter service area handoffs since the data objects interest may not be cached in the new proxies. To address this problem, we propose in this paper a novel cache capacity allocation scheme to combine the advantages of the prior cache capacity allocation schemes. A cache relocation scheme is then proposed on the basis of the designed cache capacity allocation scheme to address the problem caused by user mobility.
