Abstract

Due to self-organized network without any basic infrastructure and central equipments, it is scalable and fault-tolerant, and we believe that it must be a main direction of next generation communication network and Internet. However, because of the lack of central authority, building trust among all nodes contained in a self-organized network would become more difficult. In this paper, we propose a universal reputation system and make it reliable, lie-tolerant and DoS immunity through multidimensional reputation model, adapted discounting algorithm, recommendation game, secure reputation protocol and fault-tolerant framework. Furthermore, we demonstrate its robustness and high efficiency through example and simulation.
