摘　　要：通过对非结构化P2P网络中的随机节点选择算法进行研究,运用模糊理论中的直觉模糊集概念提出了基于得分函数的节点选择策略,以克服传统策略的随机性和盲目性。采取对节点的可靠度进行得分排序的方法,充分利用了能力强的节点,其具有良好的适应性,可反映P2P网络中节点和资源的动态性,提高了系统的整体效率。Through studying random node selection algorithm of unstructured P2P networks, By applying the theory of intuitionistic fuzzy set and put forward a node selection strategy which based on the score function, in order to overcome the randomness and blindness in the traditional strategy. This paper adopt scoring method of nodes reliability,make full use of good nodes, It has good adaptability, and can reflect the node and resources dynamic in P2P network, Meanwhile it improve the overall efficiency of the system.
