Abstract
This paper analyzes several related parameters of multimedia data flow transmission with applied technology in wireless network environment and establishes simulation model in NS2, In view of the low bandwidth, the high error rate and the high delay of wireless networks, Through the simulation analysis of the different packet error rate, the compression quantization parameter, the length of GOP and packet for image quality based on the PSNR evaluation method respectively, the result of the simulation analysis provides the beneficial reference for the wireless network of more effectively in multimedia data transmission.
