ANALYTICAL AND SIMULATION MODELS FOR QUALITY EVALUATION OF VIDEO STREAMING TRANSMISSION VIA WIRELESS NETWORK

(STEF92 Technology, 2019-06-20, L. A. Muravyeva-Vitkovskaya)

Show more

The paper deals with the actual problem of assessing the quality of video content transmission in modern wireless networks. A review and analysis is made for the quality level of the currently most popular protocols and technologies for transmitting video content in wireless networks. It analyzes video content transfer technologies based on the HyperText Transfer Protocol (HTTP), namely HTTP Progressive Download (HPD) and HTTP Adaptive Streaming (HAS). For HTTP Progressive Download and HTTP Adaptive Streaming tech...

ASSESSING THE QUALITY OF OPERATION OF WIRELESS TRAFFIC CONTROL SYSTEMS

(STEF92 Technology, 2019-06-20, L. A. Muravyeva-Vitkovskaya)

Show more

The paper proposes an analytical and simulation model of a sensory distributed wireless traffic control system on the roads of urban and rural settlements. The results of an analytical review of neurophysiological studies of the visual behavior of drivers, depending on the boundaries of the outdoor advertising area in the roadside, are presented. The technologies for collecting and transmitting data from the wireless monitoring of the road traffic situation were analyzed. A method is proposed for determining the p...

EVALUATING THE EFFECTIVENESS OF DATABASE NORMALIZATION CONSTRAINTS IN MEDIA STREAM PROCESSING APPLICATIONS

(STEF92 Technology, 2019-06-20, L. A. Muravyeva-Vitkovskaya)

Show more

The paper deals with the inefficiency of data normalization in media stream processing applications. In the classical approaches, while building a relational database architecture, developers strive to maximize the normalization of the database and bring the business logic of the system to external applications. Normalization and business logic separation have reached their apogee in object-relational mapping systems. Telecommunication systems have their own specifics. Due to the requirements for the quality of se...

MODEL AND QUANTITATIVE ASSESSMENT OF THE EFFECTIVENESS OF EXISTING METHODS OF PROTECTION AGAINST MALWARE

(STEF92 Technology, 2019-06-20, L. A. Muravyeva-Vitkovskaya)

Show more

The main ways that are used to solve problems and create mechanisms for protecting information are generally considered to be: technical devices, the whole set of which is divided into: physical and hardware - and software - programs designed to perform actions aimed at ensuring the protection of information. As a result of the development of computer security and information technologies, experts have concluded that the use of any one of the above methods will not provide reliable information protection. The comp...

QUALITY ANALYSIS OF THE COMBINED MODELS OF FIBER-OPTIC COMMUNICATION SYSTEMS FUNCTIONING

(STEF92 Technology, 2019-06-20, L. A. Muravyeva-Vitkovskaya)

Show more

The paper solves the actual problem of assessing the quality of data transmission over atmospheric optoelectronic communication lines in computer networks. The topologies of the simplex infrared data transmission channel are analyzed. The calculation of the optical system is reduced to determining the fraction of the radiated infrared power that falls on the photodetector. The total loss of the optical information signal is determined due to the mismatch of the parameters of the transmitter and receiver of the inf...
