中文摘要:
      对等网的高度动态性、异构性、关联度低等特性,要求对等网中的节点之间要高度合作.与采用激励机制促进节点之间进行合作的方法不同,本文引入强互惠理论,解决对等网络中存在的节点不合作问题,即对等网络中存在的强互惠节点,为了公平,愿意自己承担成本来惩罚不合作节点.在理论上对系统中节点的行为演化过程进行了分析,仿真实验结果显示系统中不合作节点比例降低,且提高了系统的整体收益.
英文摘要:
      Peer to Peer(P2P) network is high dynamic, heterogeneous and low correlation degree. The cooperation of nodes is important for the P2P Network. Some researches use incentive mechanism to promote the cooperation of nodes. Different from the currently study, strong reciprocity theory was introduced to solve the non cooperation problem. Namely, there are some strong reciprocity nodes in the P2P network. Strong reciprocity nodes voluntary punished the non cooperation nodes for the fairness, even though they payed the cost themselves. The nodes’ behavior evolvement in the system was analyzed in theory. The simulation results show that the non cooperation ratio is decreased and the whole payoffs is improved in the system.
