Abstract

In modern networking, peer-to-peer (P2P) file sharing remains one of the primary protocols of file distribution thanks to its decentralized nature and self-scaling. However, prioritization mechanisms in these networks significantly impact performance and fairness among peers. This project evaluates priority-based sharing in the BitTorrent protocol using ns-3 simulations which will provide insights into optimizing P2P file-sharing strategies, balancing fairness amongst users, and efficiency in real-world networks.

We would like to thank the ENSC 427 teaching team for their lectures and feedback on our project throughout the semester. We would also like to thank ns3simulations for providing us the insight to create the network topology and modify it to our project needs.
