Performance of Routing Protocol in MANET with Combined Scalable Video Coding

Development of wireless network technology to support various types of information services continues to increase especially in video streaming services. Video transmission especially in Mobile Ad Hoc Network (MANET) environment used in this research, particularly in the Combined Scalable Video Coding (CSVC) scheme which is a development of H.264 / MPEG-4. The contribution of this research focuses on the analysis of the performance of AODV, DSDV and DSR routing protocols in the MANET environment for CSVC, which is a new scheme in the development of H.264 / MPEG-4  video schemes. Performance evaluation are measured using the NS-2 simulation that supports MANET environment. As test metrics in this study are the end-to- end delay and PSNR. The test result shows the end-to-end delay in AODV is 0.60 seconds; this is lower than results on DSDV and DSR. On PSNR, DSR simulation results show 16.2 dB. This result exceed those in AODV and DSDV. The results of this research evaluation are influenced by channels in wireless networks, the larger the wireless network channel the more streaming video frames can be accepted by the destination node.  

Kinerja Protokol Routing Pada Lingkungan Wireless Mesh Network Dengan Combined Scalable Video Coding

Teknologi wireless mesh network (WMN) yang beroperasi pada standar IEEE 802.11 merupakan teknologi jaringan nirkabel terdiri dari mesh router dan mesh client dipadukan dengan internet, teknologi seluler dan jaringan sensor. Seiring perkembangan teknologi dan meningkatnya kebutuhan manusia, transmisi video melalui jaringan nirkabel semakin penting dan dibutuhkan. Umumnya, pembahasan transmisi video melalui teknologi jaringan nirkabel masih secara umum, sehingga memberikan tantangan dalam penggunaan throughput, end to end delay, packet loss dan PSNR. Combined Scalable Video Coding (CSCV) merupakan skema baru perkembangan dari H.264/MPEG-4. Pada penelitian ini CSCV digunakan untuk pengiriman video dengan standar IEEE 802.11 pada lingkungan WMN dan diaplikasikan pada protokol AODV, DSDV dan DSR. Untuk mengetahui kinerja protokol routing mana yang lebih baik dalam transmisi video CSVC digunakan metrik pengujian end to end delay, throughput, packet loss dan PSNR. Untuk analisis dan pengukuran data digunakan simulator NS-2, dan hasil percobaan simulasi yang dilakukan menunjukkan AODV memiliki nilai end to end delay yang rendah yaitu 0,57 detik, DSR memiliki nilai yang baik didalam throughput yaitu 31 kbps dan PSNR yaitu 22,7 dB, sedangkan DSDV memiliki packet loss yang rendah yaitu 56,4%

Adaptive cross-device videoconferencing solution for wireless networks based on QoS monitoring

The increase in CPU power and screen quality of todays smartphones as well as the availability of high bandwidth wireless networks has enabled high quality mobile videoconfer- encing never seen before. However, adapting to the variety of devices and network conditions that come as a result is still not a trivial issue. In this paper, we present a multiple participant videoconferencing service that adapts to different kind of devices and access networks while providing an stable communication. By combining network quality detection and the use of a multipoint control unit for video mixing and transcoding, desktop, tablet and mobile clients can participate seamlessly. We also describe the cost in terms of bandwidth and CPU usage of this approach in a variety of scenarios

Adaptive CAC for SVC Video Traffic in IEEE 802.16 Networks

International audienceCall Admission Control is a key function that guarantees the Quality of Service (QoS) for users. In radio networks, this function is usually based on traffic models and ensures that sessions are admitted only if the estimated available bandwidth is enough for the entire call duration. For video on IEEE 802.16, the CAC function must ensure that the bandwidth to be reserved is compatible with the resource availability. For the enhanced SVC (Scalable Video Coding) systems, the CAC function must take into account all the layers and their characteristics. In this paper, we propose an enhanced CAC function for SVC that adapts the admission according to the statistical behaviour of the video sessions. The main goal is to use measurements in the 802.16 base station (BS) to update the traffic model of SVC video flows, this for the different layers of SVC flows. We then use the variability of the traffics generated to adapt the CAC according to the characteristics of incoming flows. To perform that, we use a Markovian model that adapts for each flow instead of using a generic static one as used in most of the papers. Performance evaluation is given to illustrate the interest of our proposal

Random Linear Network Coding for 5G Mobile Video Delivery

An exponential increase in mobile video delivery will continue with the demand for higher resolution, multi-view and large-scale multicast video services. Novel fifth generation (5G) 3GPP New Radio (NR) standard will bring a number of new opportunities for optimizing video delivery across both 5G core and radio access networks. One of the promising approaches for video quality adaptation, throughput enhancement and erasure protection is the use of packet-level random linear network coding (RLNC). In this review paper, we discuss the integration of RLNC into the 5G NR standard, building upon the ideas and opportunities identified in 4G LTE. We explicitly identify and discuss in detail novel 5G NR features that provide support for RLNC-based video delivery in 5G, thus pointing out to the promising avenues for future research.Comment: Invited paper for Special Issue "Network and Rateless Coding for Video Streaming" - MDPI Informatio
