Information dissemination evolution under group feedback

In this paper, based on the feedback mechanism from perspective of network groups, evolutionary characteristics and laws group networks under information dissemination are studied. First, is divided into groups different sizes, each given a dynamically changing activity positive degree response to categories information. Second, feedback-based model in developed, which takes account differences between same-group cross-group Next, applied scale-free small-world for simulation experiments. The experimental results show that, mechanism, main factor affecting final size positivity, has little relationship with initial size; similarly, average also nothing do degree. Finally, method real verify rationality effectiveness proposed model.
