Design and Analysis of Credit Network over DHT File-Sharing Network

摘要

P2P file sharing networks usually are made up of selfish peers, who will harm the network availability greatly by their free riding in file sharing. Credit exchange is a mechanisms and credit relationships form a credit network. The constructing and routing algorithm in credit networks are proposed to prevent free riding and as far as possible to decrease the cost of the mechanism. Simulations prove the effectiveness and stability of the incentive mechanism.
