Abstract : As there is no distinction between client and server nodes in a peer-to-peer (P2P) network, nodes (or peers) shares resources with each others. Such setting guarantees that more resources like CPU, storage, and bandwidth are available for other peers when more nodes enter the network. BitTorrent is a predominantly usedfor distributing large files quickly and efficiently.It is a scalable peer-to-peer file distribution mechanism. As per the measurement studies, BitTorrent achieves a remarkable and excellent uplink and downlink utilization, but several issues related tolink utilization in simulation settings, fairness, and choice of BitTorrent’s peer and piece selection mechanismscan be enhanced. Piece selection plays a significant role in the Bittorrent protocol, because the Bittorrent system can be viewed as a market where peers exchange their pieces with one another.This paper proposes a comparative study of various piece selection strategies in terms of fairness, link utilization based on fuzzy logic reasonings.The proposed technique is evaluated based on the link utilization and fairness through various scenarios.
