Improved unchoking policy for BitTorrent

Peer to Peer communication has become very popular these days. This popularity has resulted into enormous increase in P2P traffic, which has given birth to many internet traffic management problems for ISP´s. Cross network traffic is major concern for ISP´s, which arise from p2p file sharing systems due to its blindness towards physical topology. Various solutions have been suggested so far, but all are implemented from client peer side. This cause load balancing problem in the overlay, where some peer have huge numbers of request while other have few service request. So we have suggested a peer selection algorithm which is implemented on serving peer´s, it takes upload rate and hop distance both while deciding which peer it should unchoke. Our suggested Dynamic peer selection algorithm tries to maintain low free riding and low cross network traffic by unchoking local peers with high upload rate capability and also act as a suitable solution for load balancing problem.
