Abstract：Fuzzy community structure can effectively improve the network transmission performance. In this paper, a new link rewiring strategy, community combination information link rewiring strategy (CCLS), is proposed based on the community structure and definition of link importance by using the assortativity or dissortativity between nodes and kcorestructure, which can delete links within the community and add links between communities to weaken the community structure and improve the network capacity. In order to verify the effectiveness of the method, we carried out simulation experiments on pseudo-random network, CWS small-world network with community structure, scale-free network with community structure and real network respectively. The simulation results show that CCLS strategy can effectively weaken the network community characteristics, and improve network transmission capacity.
