Simulation Techniques for Peer-to-Peer Information Sharing Networks

In recent years p2p file sharing networks have become extensively widespread in terms of popularity and the number of applications. Besides free file sharing software new commercial p2p based products arise as well to share large amount of information through the Internet. These trends make performance issues – in addition to scalability and robustness – come forward. Despite the growing demand simulators available for public focus only on the protocol aspects of p2p technologies and disregard performance related issues. In this paper we introduce simulation techniques to evaluate the performance of p2p information sharing applications with respect to scalability, accuracy and speed. We also tested our proposed solution and compared it to analytical results.
