QoS Optimization for Multimedia Streaming Using Hybrid RRM and DASs Over LTE Networks

Abstract

According to the nature of streaming technologies, it is very sensitive to packet loss and has strict minimum speed requirements. Network QoS metrics is proposed in order to evaluate streaming video and audio data over wireless networks under the effect of two techniques RRM and DASs. The objective of this paper is to improve QoS for streaming audio and video content over LTE networks for all users at the minimum delay and higher throughput rates. In this paper, we investigate the performance over LTE networks by the combination of these techniques to enhance the overall system performance. The Simulation results show that LTE makes a great enhancement for multimedia streaming systems under the effect of combination between both techniques DASs and RRM where it can lead to a significant and QoS enhancement by minimizing packet losses and maximization for packet delivery with total enhancement for network performance by 80 % for voice and 70 % for video streaming packets.Keywords Long term evolution (LTE) ⋅ Orthogonal frequency division multiplex (OFDM) radio resource management (RRM) ⋅ Distributed antenna systems (DASs) ⋅ Quality of service (QoS) ⋅ Quality of experience (QoE)

Appraising the Research Trend of Energy Utilization Problem in Cellular Network

“…A quick look into the existing reviews of various experts as well as researchers claims that there are 4 different consequence arising from energy problems in cellular network e.g. i) throughput, ii) bandwidth, iii) network performance, and iv) end-to-end delay [4]. In order to address energy efficiency for upcoming cellular network, it is essential that various upcoming technologies, energy saving protocols, cognitive radio, novel architectures etc.…”
