Efficient Multimedia Transmission over Scalable IoT Architecture

Abstract

Abstract-Today the new technology concept, called "Internet of Things" (IoT), presents a significant field of research, due to the fact that it promises many advantages to the users worldwide. Besides this, multimedia file streaming tends to be a daily user habit, as a result of the evolution of the internet and the capabilities of devices, such as mobile phones and computers. This tendency has established Cloud Computing (CC) as a vital technology due to the fact that it reduces economic costs, improves accessibility and flexibility, while it increases the total network performance too. This paper demonstrates a new technological approach for IoT architecture, where a layered implementation with the use of many cloud servers can offer optimized streaming and download, because of the significant reduction of the transfer time costs and the storage space of the Main Cloud Server (MCS). Moreover, users will have the ability to choose or adapt to their devices' restrictions, between low -up toUltra-High Definition (UHD) quality for multimedia access and downloading, thanks to a new quality scalability feature which is introduced and is based on the new High-Efficiency Video Coding (HEVC) compression standard. Experimental results show the efficiency of the proposed approach with math formulas and graphs.

Development of methods to improve noise immunity in the fifth­generation mobile networks based on multiposition signals

“…In addition, in contrast to methods proposed in [7], there is a possibility to form the multidimensional signals, which could provide for the modulation of different multiplicity. Another resolved task is the efficient allocation of dynamic resources, similar to OFDMA systems [8] with sufficient quality in the information transmission channels.…”

“…Thus, taking into consideration the natural constraint for signal's energy, we obtain: That is, it is necessary to find such a totality of coefficients α i , which satisfy condition (8), at which sum (7) reaches a minimum.…”

“…A given problem, stated as (7), (8), belongs to a class of nonlinear programming tasks. One of the methods to solve it is to reduce it to a certain system of equations.…”

“…Study [7] suggested methods for forming a multidimensional signal, which could not provide for the modulation with different multiplicity. Paper [8] proposes methods for effective distribution of dynamic resources in OFDMA systems employing the Packet Firefly algorithm. However, the quality of information communication channels does not make it possible to effectively apply this algorithm, as the percentage of lost packets would exceed the permissible value.…”

A system of indicators and criteria for evaluation of the level of functional stability of information heterogenic networks

“…In this regard, it is necessary to integrate heterogeneous networks into one heterogeneous system with a common management system that uses a cognitive approach and is endowed with functions of self-organization under the conditions of the influence of destabilizing factors. The network structure should support thousands of new directions, and, the most important, it should be aimed at maintaining not only the consumer subscriber sector, but also at the maintenance of such fields as manufacturing at plants, power engineering, health care, and transport, municipal realm and others [6]. Therefore, such a network must be highly resistant to all types of destructive effects and their impact factors.…”
