Performance Analysis of Video Transmission Over IEEE802.11n Wireless Networks

Multimedia services over wireless networking environment have become increasingly popular, especially for the online video streaming services and applications. This research analyzes the performance of video transmission over IEEE 802.11n in term of throughput, delay, and peak signal to noise ratio (PSNR) to find the characteristics of video streaming over a wireless network and to also propose a method to improve the transmission performance. Videos on YouTube from various categories were employed as a video dataset for evaluation in this research. Video splitting, video blending, and optimized reconstruction were proposed as video pre-processing and video reconstruction techniques used for enhancing the transmission usage and the quality of the transmitted video. Results indicated that the approach can improve the PSNR to the desired level.
