A Novel P2P Mobile Proxy Caching Scheme

In this paper, a novel P2P mobile caching scheme for caching Web documents in mobile base stations is proposed. In this scheme, a mobile cache model is used to facilitate the data cache and data replication. A self-configured and self-managed proxy overlay network is employed to fulfill the P2P data search and proxy server cooperation. Using the proposed caching scheme, the individual proxy in the base station makes cache decisions based solely on its local knowledge of the global cache state so that the entire wireless proxy cache system can be efficiently managed without centralized control. Furthermore, the proposed P2P mobile caching scheme can take advantage of the mobile host movement to improve the proxy caching performance. It is proven by formal analysis and simulation studies that the proposed P2P mobile caching scheme outperforms other caching schemes in terms of different performance metrics
