P2P Systems Research Group

The goal of the Peer-to-Peer Systems Research Group at Bilkent University is to investigate research issues in peer-to-peer systems and come up with solutions to the problems identified. The focus is on databases, networking, and security aspects of peer-to-peer computing. The current projects include: developing mechanisms and policies to prevent free-riding in peer-to-peer systems, developing schemes to reduce the flooding overhead in unstructured peer-to-peer networks, and supporting peer-to-peer applications over wireless ad hoc networks.
