Abstract:

In this paper,a cooperation-guaranteeing mechanism based on altruism punishment in mobile peer-topeer networks is presented,which takes into consideration the existence of altruism punishment widely observed in a lot of experiments in behavioral economics. In this mechanism,it is supposed that some nodes in the system have the predisposition to punish the selfish nodes with non-cooperation behaviors,even though they may receive lower payoffs or nothing. The selfish nodes are thereby restricted and their non-cooperation probability is reduced. Theoretical analysis and numerical simulation show that the proposed mechanism is reasonable and effective in reducing the number of selfish nodes and improving the cooperation.

Key words: mobile peer-to-peer network, cooperation, selfish node, altruism punishment
