A. B. Krohaleva, V. M. Belov "General model of assessing the quality of socially significant operations: "Information Security" direction "  // More...

The article proposes a general model for assessing the quality of socially significant activities (SSA), using the example of Information Security (IS). The role of IS in the structure of SSA is indicated. Assessment of the quality of information security as SSA is defined as the results taking into account the human factor (HF). The definition of HF is proposed in the context of SSA. To describe the component composition of the integral indicator, HF classification on various grounds is defined: the form of implementation, the nature of interaction within the system, the content of knowledge, the subject of HF. The main approaches to the assessment of HF are analyzed. A general model of SSA estimation is proposed, involving expert evaluation and subsequent data analysis using linguistic, point and interval scales. As expert evaluation of block methods, the classification methods of cluster and discriminant analysis are presented. From the context of SSA, the methods of nominal classification are indicated, in particular, the method of constructing classes based on entropy class calculation.

A possibility and necessity of using a radio channel for telemetry compared with the acoustic and electromagnetic communication channels are carried out. A graphic code has been designed. Description of block diagram modules for software is shown. Front panel sides of subroutines are presented.


A. Baharev, B. Zelentsov, V. Maksimov, V. Shuvalov "Congestion control algorithms applied in P2M transport protocol"  // More...

This paper considers two congestion control algorithms applied in P2M transport protocol. P2M is a reliable data transport protocol targeting a field of point to multipoint data delivery. It features an ability to maintain up to 10 simultaneous data streams (1gbps), or more, but with lower data rate. Combination of ITEA and LTEA congestion control techniques enables P2M to be RTT and loss-tolerant. This is an essential feature while in real world there will never be multiple data streams with the same medium parameters. This paper reveals some of the statistical analysis results and describes different protocol states in terms of proposed congestion control solutions.


A. Gavrishev, A. Zhuk "Generalized algorithm of secure information exchange"  // More...

In this article, the authors summarized known technologies in the form of algorithm for secure information exchange in wireless security systems, based on re-writable drives of chaotic sequences. The developed algorithm can find application in various areas of wireless security systems that require protection of the transmitted radio alarming and service messages from unauthorized access.


B. Lemeshko, S. Lemeshko, I. Veretelnikova, A. Novikova "On the application of checking criteria for homogeneity of means"  // More...

Prerequisites for application of parametric and nonparametric criteria for hypotheses testing on the equality of means are examined. Convergence of statistical distributions of nonparametric criteria to asymptotic ones is investigated by methods of statistical modeling. Comparative analysis of parametric and non-parametric criteria powers has been carried out. Recommendations on criteria application are given.

V. Utkin, V. Korotkov, D. Voynov "Wavelet filtration application while radio technical monitoring"  // More...

Based on the results of simulation modeling, the article gives a comparative analysis of wavelet filtration quality of the frequency temporal portraits of radio signals due to the noise component filtration.


R. Abenov, E. Rogozhnikov, D. Pokamestov, Ya. Kryukov, A. Demidov "Channel estimation problems in FBMC systems"  // More...

An orthogonal multiplexing technique using a filter bank is considered. A mathematical model of FBMC signal is also considered. Reasons of intrinsic interference interrupting the channel estimation are presented. The influence of the intrinsic interference during a process of forming the signal along with the use of the offset QAM is shown.


T. Belova, A. Ponachugin "Formulating of an approach to assessing the quality of Internet services and identifying the optimal providers"  // More...

The article considers background, current state, and future perspectives of the providers development. The main problems related to the facilitation of the Internet services were investigated. Current and new ways of solving the problems are presented, enabling users to choose the optimal variant of the Internet connection for themselves or their company. As a solution, it was suggested to focus on the choice of the optimal provider, as the quality of services basically depends on this factor.


A. Leonov, G. Litvinov "Application of the BeeAdHoc bee colony algorithm for routing to FANET"  // More...

FANETs are ad hoc networks based on unmanned aerial vehicles. Design of such a wireless network may vary vastly from existing networks due to aerial network characteristics such as high mobility of UAVs in 3D space. This paper presents experimental performance results that prove the advantages of the effective usage of protocols based on bee colony algorithm to solve routing tasks in FANETs.
