This paper puts forward a designing method of Dependable Network System Security Risk Diagnosis (DSSRD). It gets reduced information table, which implies that the number of evaluation criteria is reduced with no information loss, and then, this table is used to develop classification rules and infer appropriate parameters. It’s capable of overcoming several shortcomings in existing diagnosis methods, such as a dilemma between stability and redundancy. The average speed of training in DSSRD is almost twice fast as that in SMO. The experiment implemented by this method shows a good diagnostic ability.
Missile as a kind of weapon which plays a significant role in tactical strike, strategic strike and strategic deterrent, has been at the top position of the development of weapon in all country. This paper faces to the high-speed inter-missile networking, and design the deployment of the physical layer. All the missiles within the range of node running in the air automatically form a temporarily communication network, and any missile can communicate in the range of a node. When the distance between two missiles is more than the range of signal node, the message is relayed by neighbor nodes between them. Missiles can relay with satellite by configuring the satellite gateway, and send back to missile base and control center. The experiments show that the design in this paper improve the coverage of a single data link, which make the missiles efficient exchange information in network and lay a technique foundation for cooperation between missiles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
