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%

Novel Approach for Evaluating Video Transmission using Combined Scalable Video Coding over Wireless Broadband Network

One of the main problems in video transmission is the bandwidth fluctuation in wireless channel. Therefore, there is an urgent need to find an efficient bandwidth utilization and method. This research utilizes the Combined Scalable Video Coding (CSVC) which comes from Joint Scalable Video Model (JSVM). In the combined scalable video coding, we implement Coarse Grain Scalability (CGS) and Medium Grain Scalability (MGS). We propose a new scheme in which it can be implemented on Network Simulator II (NS-2) over wireless broadband network. The advantages of this new scheme over the other schemes are more realistic and based on open source program. The result shows that CSVC implementation on MGS mode outperforms CGS mode
