This paper analyzes BitTorrent cross-swarm peer participation and geolocational distribution. The authors collected 2 terabytes of data from 16 swarms of popular TV shows, identifying 6.3 million distinct IPs. The study found significant cross-swarm participation and geolocational distribution, with Australia, Europe, and North America playing a crucial role in influencing swarm size. The results can aid in network usage prediction, bandwidth provisioning, and future network design.

Proceedings of the 9th International Conference on Cyber Warfare and Security (ICCWS 2014) pp. 287-293
This paper proposes a collaborative universal peer-to-peer botnet investigation framework to fast-track the investigative process through collaboration between key stakeholders. The framework exploits common attributes of P2P networks, including intra-peer communication, self-propagation, and node maintenance, to identify and record communication patterns. This enables the elimination of duplicated work by forensic investigators and facilitates the investigation of any known botnet and adaptation to new networks.
PhD Thesis
This PhD thesis explores the investigation of Peer-to-Peer (P2P) networks, which are vulnerable to cybercrimes such as botnet propagation and malware distribution. The Universal P2P Network Investigation Framework (UP2PNIF) is introduced to facilitate faster and more efficient investigations of P2P networks.
