Fifth Collaborative Peer-to-Peer Systems (COPS 09)

The workshop is a small, high quality and interactive meeting for novel P2P ideas and proposals. On the one hand, collaborative P2P systems aim to benefit from the huge amount of unused resources of desktop computers (content, data storage, cpu, bandwidth) to create the next generation of Internet Infrastructures. On the other hand, P2P is particularly challenging for developing collaborative information systems. In this line, P2P can be used to create social networks and communities, to discover users and information, to aggregate community contents or even as a communication medium for large groups. The Fifth International Workshop on Collaborative Peer-to-Peer Systems has attracted high quality submissions from top research groups around the world. It received 27 submissions from 14 countries and it is creating a vibrant community of researchers in the peer-to-peer topic. After the review process, 10 full papers, and 1 short paper were included in the final program. The high quality submissions have demonstrated the relevance of the topic and the recent trends in the peer-to-peer research community. The workshop was divided in three sessions: algorithms, middleware and security. Every paper addresses a hot topic in peer-to-peer research and relevant researchers in the area presented their recent contributions.
