Abstract

Packet losses and delay of transmission multimedia streaming data represent enormously effective problems that effects directly on the overall system quality of service (QoS). There are numerous efficiency metrics that reflect the high-quality on data for video and audio streaming such as (i) packet loss; (ii) end-to-end delay; (iii) Packet’s Throughput; (iv) signal to noise ratio (SNR); (v) bit error rate (BER); and (vi) mean opinion score (MOS) through comparing between these Scheduling techniques with overall performance evaluations depending on testing the quality of these methods. In this thesis the selective scheduling techniques had been discussed and simulated; the proposed scheduling became carried out on video and voice streaming over worldwide interoperability for microwave access (WiMAX) and long-term evolution (LTE) networks. The main purpose of this thesis is to improve the overall performance of streaming data packets (voice and video) over fourth generation (4G) networks at different states of :(i) power;(ii) distances;(iii) modulation schemes;(iv) antennas ; and (v) network’s connections, using radio resource managements (RRM) and distributed antenna systems (DASs); also the impact of 4G networks at the overall performance of streaming data has been presented as a characteristic of network’s coverage area to study the way to growth system capacity to solve the limitation of streaming data bandwidth. Simulation results had shown that: (i) WiMAX allow making IPTV transmission from everywhere as it increase coverage area and also growing number of IPTV connections while using smart antenna techniques; (ii) LTE makes a high-quality enhancement for multimedia streaming systems under the effect of combination between both strategies DASs and RRM where it could cause QoS enhancement by minimizing packet losses and maximization for packet delivery with total enhancement for network overall performance by using 80 % for voice and 70 % for video streaming packets; and (iii) video streaming below the effect of Co-Channel interference (CCI) and MBMS services best doesn’t fulfill the requirements of performance but by means of using jammer nodes and video streaming with MBMS over LTE-A networks maximum of QoS requirements will be progressed with 80 % and supported fair quality for all network’s subscribers.
