摘要: 现有的信用管理模型采用泛洪方式获得网络节点的历史信息,其通信量和算法复杂度制约了对等(P2P)网络的应用规模。为此,综合考虑节点及节点行为多样性,在P2P网络中引入网络激励模型,使P2P网络信用管理模型具有网络适应性。分析资源区分信用管理激励模型DiffTrust,并在其基础上提出适应节点同时与多个节点进行资源交易应用环境的MultiTrust模型。实验结果表明,该模型具有更好的节点阶段收益和更短的信誉恢复时间。

Abstract: Current trust administration models based on global reputation by using flooding method have high time complexity and excessive incurred packets, thus limit the scalability when applied to Peer to Peer(P2P) networks. With comprehensive consideration of nodes and behavioral diversity in the P2P network model allows the introduction of incentive P2P network model of credit management more network adaptability. This paper analyzes the resources discrimination trust administration models scheme DiffTrust, and proposes while its foundation the adaptation node and many nodes carry on the resources transaction application environment the MultiTrust model. Experimental results show that MultiTrust model has better stage earnings and shorter credit recovery time.
