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 hand-off occurs when a user moves from the service area of one proxy to that of another. Some cache misses may be in-curred 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 ca-pacity allocation scheme to combine the advantages of the prior cache capacity allocation schemes. A cache reloca-tion scheme is then proposed on the basis of the designed cache capacity allocation scheme to address the problem caused by user mobility
