摘　　要：借鉴经济活动中的协商机制提出一种面向协商的P2P激励机制。文件供求节点通过订立协议对双方的行为进行制约,新节点和信誉度较低的节点也可以通过订立协议参与文件交易,达到提高节点的文件交易成功率的目的。仿真结果表明,该机制有效抑制了搭便车行为,明显提高了网络文件资源的利用率。In reference to the negotiation mechanism in economic activities,a kind of P2 Pincentive mechanism for negotiation was put forward.The behaviors of the nodes of the sharing file supply and demand were restricted by the trade agreements.So the nodes with lower credibility and new nodes could enter into the agreement to participate in the documents transactions,which reached the destination of improving the success rate of the documents transaction of these nodes.Simulation results show that the proposed incentive mechanism suppresses free-riding behavior effectively,network file resource utilization in the P2 Pnetworks is significantly improved.
