The paper studies the problem of complex safety in personal area network and local area network in the Internet of Things project's boundaries. The electromagnetic safety analysis of various wired, wireless and fiber-optics technologies have realized by statistical simulation with applying the spatial analogue of the Huygens- Kirchhoff principle. The model of equivalent radiator for estimation of Internet of Things objects safety is offered. The simulation results of the statistical model in the form of histograms of the field strengths levels of the electric E-field and magnetic H-field, their phase and polarization characteristics must be interpreted and adapted in relation to the problems of specific engineering. Recommendations for the selection of personal area network and local area network elements are given.
The paper presents results of statistical simulation (SS) of a distributed random antenna (DRA) using the triad-cluster method (TCM) with a basic element in the form of a triad elementary radiator (TER) and the spatial analogue of the Huygens-Kirchhoff principle. Ways of solving internal and external problems, including the formulation of the initial conditions and the principles of studying characteristics of the electric and magnetic field strength vectors for TCMmodels of DRA are considered. The presented results of DRA study demonstrate the statistical characteristics (histograms of levels) of the E-field and the H-field strengths, which make the decision maker (DM) possible to understand and reproduce the physical processes that accompany formation of the EMF-channel of confidential information leakage via DRA.
The paper presents the results of statistical simulation (SS) of multi-element aperture random antenna (ARA) by triadcluster method (TCM). The problem is formulated in a general form and the described method is valid for all electromagnetic phenomena, including the optical range. As the wavelength decreases, the correctness of the proposed approach increases. The base element of ARA is a triadic elementary radiator (TER), which consist of orthogonal electric and magnetic radiators. The components of TER are excited by random in amplitude, phase and direction electric and magnetic currents. Histograms of levels of electric and magnetic field strength at frequencies from 1 KHz to 10 GHz are presented. Comparative analysis to study effect of wave fields’ combinatorics, which creates by components of TER and phase errors, on SS results was made. The case of joint impact of the combinatorics, amplitude and phase errors on TCM model of ARA is considered.

In this paper, we discuss simulation of statistical characteristics of electromagnetic field exciting the aperture random antenna in the most general and close to reality case, with application of the method of statistical simulation and computer version of Monte Carlo methods. A triad elementary radiator model instead of Huygens radiator is proposed as basic element of a random antenna. A relation between virtual currents exciting an aperture random antenna and orthogonal components of a real electromagnetic field vectors is obtained and proved. The histograms of excitation currents distribution of triad elementary radiator are obtained. The possibility of applying single-mode probabilistic laws to simulate virtual excitation currents of a triad radiator is proved. The validity of using random errors generation according to the uniform distribution law during statistical simulation is proved.
