A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks

The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...

Modeling and Generation of Self-similar Behavior of Mpeg-4 Video Traffic Using Chaotic Maps Method

The rise in popularity of the Internet, and specially the World Web Wide, has resulted in the web browser becoming the most commonly used Internet application. This popularity has driven the increase in multimedia applications with streaming audio and video players becoming almost ubiquitous. These audio and video traffics represent a new class of Internet traffic, which will increase with intr...

Impact of Various VoIP and Video Traffics to Performance of Aggregation with Fragment Retransmission (AFR) in WLAN

Agregation With Fragment Retransmision (AFR) is a frame transmission scheme that can improve the efficiency and the throughput of MAC layer in WLAN 802.11n. In this paper, we studied the performance of AFR scheme when various VoIP and video traffics transmitted over WLAN. The purpose of this work is to know how the number of connections, packet size and fragment size of VoIP and video traffics ...

Traffic Analysis and Modeling of Real World Video Encoders

Any performance evaluation of broadband networks requires statistical analysis and modeling of the actual network traffic. Since multimedia services and especially MPEG coded video streams are expected to be a major traffic component over these networks, modeling of such services and accurate estimation of the network resources are crucial for the reliable operation of the future telecommunicat...
