Peer-to-peer applications (P2P) are no longer limited to home users, and start being accepted in academic and corporate environments. While file sharing and instant messaging applications are the most traditional examples, they are no longer the only ones benefiting from the potential advantages of P2P networks. For example, network file storage, data transmission, distributed computing, and co...

An important issue in P2P networks is the existence of malicious nodes that decreases the performance of such networks. Reputation system in which nodes are ranked based on their behavior, is one of the proposed solutions to detect and isolate malicious (low ranked) nodes. Gossip Trust is an interesting previously proposed algorithm for reputation aggregation in P2P networks based on t...

1 INTRODUCTION This report is a survey of the literature about the topic " Collaborative P2P Systems ". In the remaining part of the report first, collaborative P2P systems with examples will be explained. Second, brief information about JXTA will be provided. Last, summary of research papers related with collaborative P2P systems will be given. P2P systems provide adaptation, self-organization...

P2P systems enable decentralised applications for supporting collaborating groups and communities, where the collaboration may involve both sharing of data and sharing of group processes among group members. In such applications, monitoring and awareness are critical functionalities required for an effective collaboration. However, to date there has been little research into providing generic, ...

We intend to propose a set of performance metrics to evaluate a peer to peer (P2P) file sharing system. P2P file sharing systems are increasingly becoming popular in the internet community for efficient and easy sharing of files among users. A group of people have to choose from several commercially available P2P clients to share their files. The available P2P networks cater to a specific type ...
