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
