Dynamic trust relationship making quantization model based on multiple attribute decision has been researched in this paper. Considering the problem that all information from nodes feedback would be not true or reliable, this paper improves a new rule to calculate the feedback trust and proposes a new quantization model on dynamic trust-relationship based on improved feedback trust. On this basis, from the complex structure characteristics of network, this paper introduces the nodes similarity and proposes a improved model of dynamic trust-relationship based on multi-attribution. The simulatio...
