Vehicular Ad Hoc Networks (VANETs) are more attracted research topic for research community in recent years. The IEEE 802.11p defined by Wireless Access in Vehicular Environment (WAVE) standard for MAC layer implementation in VANETs. IEEE 802.11p uses Collision Sense Multiple Access (CSMA) mechanism and fixed Service Channel Interval (SCHI), Control Channel Interval (CCHI) for access channels. Due...
This paper applies fuzzy clustering into clustering processing emergency rescue route according to pertinent indexes. With MATLAB software as platform to perform simulation experiment, paper finally gets dynamic clustering figure by setting up different confidence level λ. This paper aims at simplifying route choice decision to establish foundation to search shortest path.
On the basis of determining the space scale of the regional risk assessment recognized and analyzed the risk source with the systematic engineering principles and methods, and set up a fuzzy comprehensive evaluation system. And then set up the evaluation system of Petrochemical Area in Huang Dao by using fuzzy comprehensive evaluation and MATLAB and GUI technology, and it will supply technical support...
Aimed at the problems of needing to determine the weights of index system in most comprehensive evaluation methods of risk assessment in civil aviation, and the calculation was too complicated; catastrophe evaluation method was applied to the risk assessment of SMS in civil aviation. Indicators were analyzed and sorted, and then the standard of the bottom indicators was performed. The ultimate catastrophe...
