Bluetooth Mesh (BM) is a new communication standard, which is designed for the upcoming Internet of Things. It builds on the Bluetooth Low Energy (BLE) protocol and allows devices to extend the range and create a mesh network. BM introduces a publisher/ observer structure where a publisher node can broadcast a packet, known also as an advertisement, and all observers can receive the packet. Typically, in BM networks flooding is used to propagate the advertisements. Flooding is known to suffer from broadcast storm problem and be nonreli-able. To improve packet delivery ratio we propose an approach where only a few nodes, relays, are involved in packet forwarding. Selection of the relay nodes, which is a focus of the paper, is a nontrivial task: on the one hand, a minimization of number of relays is desired, on the other hand, using a minimum dominated set would not provide redundancy. We consider three different relay selection mechanisms and develop their extensions that are capable to operate in a distributed fashion. Their performance is evaluated via extensive simulations.

The computer program is proposed for a realization of the symbolic algorithm based on the quantum mechanics with non-negative probability distribution function (QDF) and for calculations of energy levels for hydrogen-like atoms. In the framework of the algorithm an original Maple package for calculations of necessary functions, such as hydrogen wave functions, Sturmian functions and their Fourier-transforms, Clebsch- Gordan coefficients etc is proposed. Operators of observables are calculated on the basis of the QDF quantization rule.

This contribution presents straightforward design of a fractional-order oscillator employing novel simple impedance inverter (implementing differential voltage current conveyor transconductance amplifier as active element) used for construction of parallel LC resonator and requiring also negative resistor. Design supposing two output waveforms with constant amplitude ratio and phase shift 155 degrees (-25 degrees) supposes two identical constant phase elements (fractional-order capacitors). The key advantages of our solution, stability of ratio of output levels and phase shift between generated waveforms, were confirmed by simulations.

Queuing systems with limited resources, in which customers require a server and a certain amount of limited resources for the duration of their service, allow modeling any peculiarities of resource allocation in modern wireless networks. Including signals that trigger resource reallocation procedures, affords an opportunity to take into account mobility of mobile terminals. However, the application of the queuing systems leads to complex computations. In this paper, we develop the simulation tool for the limited resources queuing systems with signals and provide some numerical results.

This article discusses the efficiency of the IEEE 802.11ac standard amendment from airtime resource usage point of view. An OFDM channel model is proposed as a function between its basic parameters and the application conditions. Analytical models are obtained for the data bits per OFDM symbol and the data frame transmission time as a function of the signal to noise ratio for the IEEE 802.11ac standard amendment. The model analysis shows that the error of the model is less than 6% for the most of the data frame size values. The proposed analytical models can be used to assess the effectiveness of the network and thus help in the design process of the networks.

This paper deals with design of digital bandpass filters for fixed-point arithmetic that fulfills requirements of IEC 61260–1 standard for fractional-octave-band filters. The filters use coupled form and downsampling that provides good approximation of the relative attenuation for fractional-octave-band filters and good stability at low-power fixed-point microprocessors which are essential for energy-efficient processing in sensor networks. For the 16-bit resolution, the IEC 61260–1 Class 1 requirements are fulfilled for designed octave-band filters from 63 Hz and for third-octave-band filters from 50 Hz. Implementation of the IEC 61260–1 fractional-octave-band filters in low-power noise sensors enables advanced measurements that conform international standards for noise measurements in the smart city or in other sensor network infrastructures.

The present work is devoted to the analysis and investigation of traffic in software defined networks (SDN). This article describes the main provisions of the SDN concept, the task of investigating traffic is presented, and a possible way to solve it is considered. The task of traffic research includes an analysis of the basic characteristics and traffic indicators of SDN. As a possible solution, a method of full-scale modeling is proposed. In this paper, a full-scale experiment was performed on a real network for the modeling and analysis of SDN traffic. Also in the work, the obtained result is approximated to understand to which theoretical distribution law the empirical distribution obtained in the experiment described in this article is closer. In addition, in this scientific paper, self-similarity of SDN traffic simulated to the experiment input is estimated.

Self-oscillating modes in control systems of computer networks quite negatively affect the characteristics of these networks so the investigation of parameters of self-oscillations as well as self-oscillations areas is actual. But due to the non-linear nature of usually constructed mathematical models the study of self-oscillations areas and parameters are extremely labor-intensive. It is of interest to obtain a so-called parametric portrait describing the zones of occurrence of self-oscillations depending on the value of the parameters: one parameter (two-dimensional graph), two parameters (three-dimensional graph), and so on. Such a parametric portrait allows us to purposefully manage the characteristics of the investigated control system. The paper describes a parametric study technique based on the method of harmonic linearization because in the standard mathematical model based on ordinary linearization by Taylor expansion a self-oscillation regime disappears (due to Taylor expansion linearization). To verify the theoretical results obtained, simulation is used. In addition, it is proposed to use the computer algebra system for analytical calculations. For this, the criteria for choosing software were formulated. Based on these criteria, a set of software for analytical and numerical calculations was proposed.

In this paper, we study the statistical properties of pseudorandom number sequence (PRS) generators (PRNGs) based on strong cryptographic algorithms. We propose a method for assessing the quality of PRS generators and a criterion based on the quality/speed ratio to compare output of PRNGs. It uses the results of statistical testing of generated PRSs and allows to evaluate similarity degree of sequences produced by PRNGs to true random sequences. We apply the method to study statistical properties of pseudorandom sequences produced by several generators based on popular cryptographic algorithms.
