A Cooperative Hybrid Caching Strategy for P2P Mobile Network
Recently mobile network technologies develop quickly.To meet the increasing demand of wireless users,many multimedia proxies have been deployed over wireless networks.The caching nodes constitute a wireless caching system with an architecture of P2P and provide better service to mobile users.In this paper,we formulate the caching system to optimize the consumption of network bandwidth and guarantee the response time of mobile users.Two strategies:single greedy caching strategy and cooperative hybrid caching strategy are proposed to achieve this goal.Single greedy caching aims to reduce bandwidth consumption from the standpoint of each caching node,while cooperative hybrid caching allows sharing and coordination of multiple nodes,taking both bandwidth consumption and popularity into account.Simulation results show that cooperative hybrid caching outperforms single greedy caching in both bandwidth consumption and delay time.
