Currently, BitTorrent is the most popular protocol that is widely used for P2P file sharing system. Nevertheless, BitTorrent protocol exposes some inefficient processes that are choosing neighbors and selecting pieces. These are mainly based on the knowledge of overlay topology without considering underlying internet topology that might cause of traffic problems such as the bottleneck at some point of network. Therefore, they propose the new approach for BitTorrent protocol with tracker localized algorithm, picker localized algorithm and localized algorithm which autonomous hops between peers are calculated to make efficient decisions. Then to compare the AS hop between 5 AS and 7 AS in the network.
