摘要

摘要: 现有P2P网络拓扑构造协议大多是基于节点历史行为来决定拓扑的构造方式，在面对P2P节点复杂多变的行为时无法实时地保证拓扑的有效性。该文首先利用博弈论针对不同类型节点的交互行为及收益建立博弈模型。在此基础上，提出了基于节点类型跟踪识别机制的拓扑构造协议TATP。仿真实验表明，TATP协议即使在恶劣的P2P网络环境下也能够让善意节点开始聚集，将恶意节点排斥到网络边缘，使得P2P网络拓扑具有更好的有效性和安全性，同时协议的网络开销较小。

Abstract: Most of the existing protocols construct P2P topologies based on the history of P2P nodes actions, however, they can not ensure the efficiency of the topologies in time, when facing the complexity and turbulence of P2P nodes strategies. This paper firstly builds the game model of the interactions and payoffs of various types of P2P nodes. In this foundation, this paper proposes the TATP based on the identification mechanism of P2P nodes types. The simulations show that the good nodes will begin to congregate and the bad ones will be excluded to the edge of the networks. The results also indicate that TATP will improve the efficiency and security of P2P topologies, with less network costs, even in the worst network environments.
