The exchange of correct and reliable data among legitimate nodes is one of the most important challenges in vehicular ad hoc networks(VANETs). Malicious nodes and obstacles, by generating inaccurate information, have a negative impact on the security of 5G-VANET. The big data generated in the vehicular network is also an issue in the security of VANET. To this end, a security model based on authentication and plausibility is proposed to improve the safety of network named ‘AFPM’. In the first layer, an authentication mechanism using edge nodes along with 5G is proposed to deal with the illegitimate nodes who enter the network and broadcast wrong information. In the authentication mechanism, because of the growth of the connected vehicles to the edge nodes that lead to generating big data and hence the inappropriateness of the traditional data structures, cuckoo filter, as a space-efficient probabilistic data structure, is used. In the second layer, a plausibility model by performing fuzzy logic is presented to cope with inaccurate information. The plausibility model is based on detection of inconsistent data involved in the event message. The plausibility model not only tackles with inaccurate, incomplete, and inaccuracy data but also deals with misbehaviour nodes under both line-of-sight(LOS) and non-line-of-sight(NLOS) conditions. All obtained results are validated through well-known evaluation measures such as F-measure and communication overhead. The results presented in this paper demonstrate that the proposed security model possesses a better performance in comparison with the existing studies.

Do My Loop Detectors Count Correctly？ A Set of Functions for Detector plausibility Testing

引用

Journal of Traffic and Transportation Engineering 2016年第3期4卷 117-130页

Loop detectors are wide-spread and relatively cheap detecting devices. With today＇s traffic communication revolution, high resolution detector data is available on a central traffic management level. High resolution detector data consist of detector slopes, also called pulse data. There is an initial and continuous need for checking the detectors for correct data as all kinds of disturbances may add erroneous information to the data. This paper proposes pulse data checking and interval data checking with optional data replacement in order to guarantee a continuous data flow even if detectors do not deliver the expected data quality： Raw detector data checking analyses rising and falling slopes of detector signals; Cumulative data checking compares interval values to reference curves. Cumulative data checking needs less computational effort, but needs more parameterization effort than raw detector data checking. Both checking principles are applied to different systems in Switzerland since about five years.

On the Seismic Jerk

引用

Journal of Geological Resource and Engineering 2017年第4期5卷 147-168页

作者： Ramiro Sofronie Independent Technical Expert Bucharest 030823 Romania

The paper deals with the mathematical concept of jerk created in 1825 by Carl Jacobi and introduced in 1936, forapplications purposes in dynamics by Aurel A. Beles. Extended in seismic engineering that phenomenon of dynamic amplification isbased on the first law of conservation in Mechanics combined with the theory of dislocations developed by Lev Landau. Finally, thetwo study cases presented in the paper recommend this simply analysis method for advanced practical cases with any degree ofaccuracy as well as in solving some plausibility inquire as requested by ISO 13822：2010.

On the Seismic Resilience

引用

Journal of Geological Resource and Engineering 2019年第4期7卷 132-139页

作者： Ramiro Sofronie Independent Technical Expert Bucharest 030823Romania

The paper deals with the self-defending capacity of buildings and structures against earthquakes. The idea of this conceptcomes from Hooke’s Law of elasticity published in 1678. The original deterministic concept was converted, with the aid of reliabilityanalysis, into a probalistic form. In this way seismic resilience covers a larger field of random phenomena and becomes directlyinvolved in more engineering applications.
