High Mobility Evaluation for Voice & Video over LTE

چکیده
Due to the exponential clients demand for new services with high Quality (QOS). 3GPP has developed a new cellular standard based packet switching allowing high data rate, 100 Mbps in Downlink and 50 Mbps in Uplink, this standard is termed LTE (Long Term Evolution). Beyond the improvement in bit rate, LTE aims to provide a highly efficient, low latency, spectrum flexibility and higher mobile speed performances. The purpose of this paper is to prove the high mobility performances. The performance evaluation is conducted in terms of system throughput, delay, and Packet Loss Ratio, using different scheduling algorithms implemented at the LTE base station (PF, MLWDF and EXP/PF schedulers). Finally it will be concluded that higher mobile speed performances are proved with all the 3 scheduling algorithms for best effort flows, while for Video flows the M-LWDF and EXP/PF schedulers who are more preferment , and for VoIP flows it's PF and EXP/PF schedulers who gives high performances.

Abstract The streamed audio video (AV) content for IPTV across mobile WiMAX channel, the different schemes were discussed to reduce the noise, packet loss and latency. The objective of this paper is to verify the effectiveness of forward error correction (FEC) techniques and to suggest the techniques for robustness problems and to analysis the issues either due to AV coding encoding or due to...
متن کاملThe Feedback Based Mechanism for Video Streaming Over Multipath Ad Hoc Networks
Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...
