PROJECT TITLE :

An Efficient Caching Scheme and Consistency Maintenance in Hybrid P2P System

ABSTRACT:

Peer-to-peer overlay networks are widely used in distributed systems. P2P networks can be divided into two categories: structured peer-to-peer networks in which peers are connected by a regular topology, and unstructured peer-to-peer networks in which the topology is arbitrary. The objective of this work is to design a hybrid peer-to-peer system for distributed data sharing which combines the advantages of both types of peer-to-peer networks and minimizes their disadvantages. Consistency maintenance is propagating the updates from a primary file to its replica. Adaptive Consistency Maintenance Algorithm (ACMA) maintains that periodically polls the file owner to update the file due to minimum number of replicas consistency overhead is very low.
