In peer-to-peer file sharing systems, file replication and consistency maintenance are most widely used techniques for better system performance. Most of the file replication methods replicates files in requesters or near file owners or along a query path from a owner to a requester, leading to low replica utilization, creates redundant replicas and extra expenses for consistency maintenance. Most of the consistency maintenance methods promote update messages based on message spreading or structure based methods without considering file replication enthusiasm, leading to unsuccessful file update and obsolete file response. This paper presents an Adaptive file Replication and consistency Maintenance Mechanism (ARM) that assimilates file replication and consistency maintenance mechanism that achieves higher productivity in file replication and consistency maintenance at a low cost. In this mechanism, each node specifies the need for the file replication and update polling dynamically by adapting to time-varying number of request received for the file and updates performed in that file, which avoids redundant file replications and updates. For fast data access, the user interest model deletes the unused data from memory in order to reduce the memory size. It dramatically reduces expenses and yields sudden improvements on the ability of both file replication and consistency maintenance approaches.
