Abstract

Reputation systems are proved mechanisms used to help nodes to decide whom to trust, to maintain the overall credibility of the system and to promote collaboration. This paper presents Surework, a reputation framework based on Super-peers. In Surework, peers form clusters around Super-reputation-peers (Sure-peers) who help to increase the reputation knowledge. Surework introduces incentives in order to promote that nodes with higher capabilities become Super-peers and assume more tasks than normal peers. Reciprocity is also promoted by encouraging peers to provide better services to most reputable client peers.
