Abstract
In unstructured peer-to-peer networks, the analysis of scalability is a challenging task due to the unpredictable nature of churn rate. Specifically, in the P2P file sharing applications, peers join and leave the overlay network in a dynamic fashion increase the complexity of the network and leads to a huge wastage of bandwidth during the search for a particular file. In this paper, we proposed a controlled scalability model in unstructured P2P networks for achieving efficient bandwidth utilization and high scalability. Performance measures such as peer availability and scalability are analyzed and compared with the BitTorrent system show that the proposed model overcomes the problems of bandwidth wastage and initial time flash crowd while maintaining the scalability of the network. Mathematical modeling and simulation results illustrates that the controlled scalability performs well in utilizing bandwidth during the event of polluted or infected files sharing than the uncontrolled scalability in the existing unstructured P2P networks.
