The Research Of Network Models And Immunization Strategies Based On Tibetan Web Pages

With the development of the network technology and the national language and characters processing technology, Tibetan information in the form of webpages are increasing, the number of Tibetan websites are growing at an alarming rate, Tibetan websites have become an important part of the Internet. How quickly and effectively to ensure the safety of Tibetan Web page links with huge data become one of the most urgent problems, which is also a hot spot of research of the scholars.Random immunization strategy, target immunization strategy and acquaintances immunization strategy are the three immunization strategies. For random immunization strategy, if implemented random immunization strategies in scale-free networks which need to ensure the immunity of the whole network node to eventually curb the spread of the virus; target immunization strategy need to do too much computational cost; acquaintance immunization strategy even though avoids the insufficient of first two, the immune effect does not well than target immune immunization strategy.Firstly, analyzing the Tibetan Web network topology structure, based on structural properties of Tibetan Web network, proposing reasonable immune algorithms. On the basis of Tibetan Web network model, this paper presents three immune algorithms:(1) The maximum degree immunization strategy based on Tibetan WebConsidering the inaccurate immunization goals of the acquaintance immunization strategy and consuming problem of the target immunization, this paper presents to do immune on the maximum degree of neighbors of the randomly selected nodes.(2) The double immunization strategy based on Tibetan WebThis paper improves the acquaintance immunization strategy further, every immune step is do immune on the randomly selected nodes and their neighbors with the maximum degree, this algorithm particularly fits for the networks with the characteristics of small-world or the characteristics scale-free.(3) Immunization strategy based on Tibetan community divisionAccording to the characteristics of Tibetan Web topology and the idea of division community, dividing community of Tibetan Web network firstly before making immune, and locating for the nodes with the properties of weak connections. When begin the immune, do immune on the nodes with weak ties, then do immune according to the structure properties of community.Simulation results show that the immune effect of the three immune strategy proposed in this paper is superior to the acquaintance immunization strategy, the effect of Immunization strategy based on Tibetan community division is best of the three.
