Expansion Strategy of Power Communication Network Survivability Based on Complex Network
摘要
Abstract
With rapid development of information and communication technologies, more and more types of services are carried in power communication network. Therefore, expansion of power communication network is urgently needed, meanwhile, vulnerability of the network need to improve, and continuity of the power communication network after failure need to ensure. Based on the theory of complex networks, this paper constructs a network model of Taicang power communication network. By analyzing the defects of BA model, this paper proposes an improved LD_CA (low distance_cluster addition) strategy. A different edge-adding strategy for expanding network capacity is adopted. According to average path length and clustering index after expansion of power communication network, advantages and disadvantages of different edge addition strategies are analyzed. Based on this, relation between clustering coefficient of power communication network robustness and network vulnerability is obtained, and connectivity of the power communication network after random node failure and specific areas attack under three strategies is analyzed. Simulation results show that the LD_CA strategy is obviously superior to RA and LDA in terms of improving power communication network performance, i.e., shortening average path length of the power communication network, reducing the clustering coefficient and improving network capacity and vulnerability.关键词
