The P2P system should be used Proximity information to minimize the load of file request and improve the
efficiency of the work .Clustering peers for their physical proximity can also rise the performance of the
request file. However, very few currently work in a peer group based on demands as peers on physical
proximity. Although structured P2P provides more efficient files requests than unstructured P2P, it is difficult
to apply because of their strictly defined topology. In this work, we intending to introduce a system for
exchange a P2P file for proximity and level of interest based on structured P2P nodes that form physically
block in the cluster and other groups physically close and nodes of public interest in sub-cluster based on the
hierarchical topology. Querying an effective file is important for the overall P2P file exchange performance.
Clustering peers from their common interests can significantly enhance the efficiency of the request file PAIS
use an intelligent file replication algorithm to further rise the efficiency of the request file .Create a copy file
that is often requested by a group of physically close nodes in their position. In addition, PAIS improves the
search for files within the intra-system sub-cluster through various approaches. First, it further classifies
interest in the sub-cluster to a number of subsections of interests and groups with common interest-free sub
nodes in the group for file sharing. Secondly PAIS creates an over for each group that connects nodes of less
node capacity to a higher throughput for the distributed node overload prevention request file. Third, in order
to reduce the search for late files, PAIS uses a set of proactive information so that applicant can file
knowledge if its requested file is in the neighboring nodes. Fourth, reduce the overhead of collecting
information about files using the PAIS, collection of file information based on the Bloom Filter and the
corresponding search for files distributed. Fifth, in order to improve the efficiency of file sharing, PAIS ranks
the results with a blob of filters in order. Sixth, while the newly visited file is usually re-visited approach,
based on the Bloom filter is improved only through the management of new information flowering filter is
added to reduce the delay of file search. The experimental result of the Real-world Planet Lab Experiment
shows that PAIS significantly reduces overhead and improves the efficiency of scrolling and without sharing
files. In addition, the experimental results show high efficiency within the sub-research cluster of file
approaches to improve file search efficiency.
