Peer-to-peer file sharing systems, most notably Bit-Torrent (BT), have achieved tremendous success among Internet users. Recent studies suggest that long-term relationships among BT peers could be explored for peer cooperation, so as to achieve better sharing efficiency. However, whether such long-term relationships exist remain unknown. From an 80-day trace of 100, 000 real world swarms, we find...
Wireless sensor networks (WSNs) have been increasingly deployed for both civil and military applications under harsh, unpredictable or open environments. Such environments create opportunities for the intruders to launch a variety of attacks on multiple protocol layers in WSNs. This paper proposes a behavior monitoring and analysis framework for large scale WSNs. Within this framework, we address...
As the Internet becomes the critical information infrastructure for both personal and business applications, fast and reliable routing protocols need to be designed to maintain the performance of those applications in the presence of failures. Today's interdomain routing protocol, BGP, is known to be slow in reacting and recovering from network failures. Increasing path diversity by advertising multiple...
