Design and Implementation of Node Cooperative Caching Policy for Opportunistic Network
Ming Zhao · Jisuanji gongcheng · 2010
Aiming at the problem of how to use the cooperative relations and limited cache resources of nodes to avoid network traffic and improve communicating performance,this paper proposes an opportunistic network cooperative caching policy,which is referred as HMP-Cache.According to the nodes movement characteristics,the standard of target address matching is used to choose cooperative caching nodes.Caching information can be shared by synchronization of caching table in local region.Simulation results show that the policy can control the network cost effectively and the network data latency is reduced.
