Our previous work proposed a MPEG-21 based P2P network architecture supporting resource adaptation on the basis of usage environment and user preferences. In this paper, we investigate the deployment of a BitTorrent (BT) - like approach in the previous super-peer P2P resource adaptation architecture. In addition, the architecture's peer selection strategy is adopted and evaluated as a way to enhance the peer selection process in BT. The strategy uses super peers as trackers to intelligently select peers according to their capabilities and shared resource segments. Simulation results show that the proposed selection strategy reduces average access time and increases download speed when compared with the existing BT peer selection process with randomly selected peers. The results also show that the deployment of BT in the P2P adaptation architecture greatly reduces the congested download problem previously reported.
