Survivability evaluation of tactical communication networks based on clustering

Conventional measures used in the invulnerability and survivability evaluation of tactical communication networks were first discussed, and shortcomings of these measures were pointed out. A new survivability evaluation measure, viz. the global network survivability based on clustering, which is applicable to tactical communication networks, was then proposed. Some properties and theorem about this measure were put forward. Simulation of survivability evaluation using this measure to 12 kinds of topological networks was finally accomplished. Comparison between this and the LCF measure was also given. The results proved that the design of global network survivability based on clustering was reasonable, and that its computation was rapid. Moreover, it can take into account the invalidation of both nodes and links, while possessing fine physical meanings.
