Abstract:

Among various searching techniques,the hot resource-based searching is focused on.In this paper,we propose an adaptive file replication method based on semantic dynamic community SARA(semantic-aware replication based on ARIMA).By introduced ARIMA prediction model and fully taken account the features of the semantics topology of unstructured P2P network,SARA copies possible hot resources in advance.The simulation results show that SARA effectively avoids unnecessary waste of copies,and reduces the replication cost.Meanwhile SARA also can guarantee a high search efficiency of the copies.

Key words: SARA, replication of the copies, prediction function, P2P network
