Distributed micro payment mechanism based on repeated game in DHT network environment

This paper proposed a distributed micropayment mechanism based on repeated game and its implementation scheme,in which the service transaction between non-adjacent nodes was formed via the middle node's debt relay.And based on the intrinsic stability between nodes' neighbor relationship,it constructed a repeated game model of the debt relationship.In addition it proved the validity of this micropayment mechanism to be effective in theory.Furthermore,taking account of the debt network's strong dynamic feature,it put forward an improved routing algorithm in DHT network.Experimental results show that this micropayment mechanism supports efficient payment in large-scale networks.
