Unveiling the Bittorrent Performance in Mobile Wimax Networks

As mobile Internet environments are becoming widespread, how to revamp Peer-To-Peer (P2P) operations for mobile hosts is gaining more attention. In this paper, the authors carry out empirical measurement of BitTorrent users in a commercial WiMAX network. They investigate how handovers in WiMAX networks impact the BitTorrent performance, how BitTorrent peers perform from the aspects of connectivity, stability and capability, and how the BitTorrent protocol behaves depending on user mobility. They observe that the drawbacks of BitTorrent for mobile users are characterized by poor connectivity among peers, short download session times, small download throughput, negligible upload contributions, and high signaling overhead.
