Peer-to-peer (P2P) overlay networks are currently being used to build large scale distributed systems running various decentralized applications like distributed storage, content distribution, collaborative scheduling, and leader election. Although we have protocols like Byzantine agreement, voting schemes etc. for building resilient distributed applications; we have very few solutions available for...
The P2P system is an anonymous and dynamic system, thus, some malicious behaviour can't be punished. In order to restrict the malicious behaviour in the P2P system, researchers have focused on establishing effective reputation systems. However, the present reputation system can't avoid the trick of the false reputation feedback. We propose a distributed trust-based reputation model in p2p system (TBRM)...
Free-riders and fake files are two important problems in P2P file sharing systems. Previous works have always used incentive mechanisms and trust mechanisms to address them respectively. In real systems however, a trust mechanism without incentive would face lack of users' enthusiasm and thus cause sparse relationship of direct trust while an incentive mechanism without trust could induce users' bad...
Awareness of social ratings such as reputation, credibility and trustworthiness plays a key role in digital ecosystems where autonomous agents collaborate in order to publish their services or search for services. The integration of these social ratings along with attribute matching presents a novel approach and strengthens stability and confidence in autonomous distributed communities. This ensures...
Peer-to-peer network can be seen as truly distributed computing system. Each peer is both a client and a server in these networks. The trust between peers cannot be set up simply on the traditional trust mechanism. A reasonable trust construction approach comes from the social network analysis. Trust relations between individuals are set up upon recommendations of other individuals. In this paper,...
Global trust value of P2P (peer-to-peer) has been studied in detail, but the base of it, local trust value, has not been explored in depth. The existent models only adopt simple methods to calculate it. These methods are based on count of success and failure times of transaction, so it cannot represent the distribution of success and failure in transaction history. It is the first time to introduce...
