Abstract: In this paper，a method of resource discovery based on social network is designed which is non-center，survivable，and self-adaptive.Through this method，the nodes can cooperate with each other to find the resources they want.And then，the model and algorithm of the method is presented.Finally，the simulation results have shown that the method can be used to improve the discovery performance，be good at adapting the different distributed resources and mode of user’s requesting，and survive in the dynamic environment of network.

Key words: distributed environment, resource discovery, social network

摘要： 基于社会网络设计了一个无中心的、可生存的、自适应的资源发现方法，使得网络节点相互协作，以发现所需资源。接着，详细地给出了方法的模型、算法。仿真结果表明该方法能够改善发现的性能、很好地适应不同的资源分布和用户请求模式以及能够从动态的网络环境中生存。
