Delivering MPEG-4 real-time video over the Internet requires the use of rate control schemes in both the compression and the transport domains. This paper discusses the practical difficulties involved in integrating MPEG-4 scalable rate control (SRC) in the compression domain with TCP-friendly rate control (TFRC) in the transport domain. In addition to the requirement for rate matching between the...
Multimedia wireless network QoS support has become one of the most important researches in recent years. IEEE wireless 802.11e is the most hopeful among these methods. However, 802.11e experiment performance metrics are essentially network-level measures. They represent the network state, not the perceptual quality of the end user. This paper presents an application-level study on the wireless 802...
The QoS support for multimedia on wireless network is one of the most important researches in recent years. IEEE wireless 802.11e is the most hopeful among these methods. However, the performance metrics used in 802.11e experiments are almost network-level measures. They represent the network state and not the perceptual quality of the end user. Besides, the wireless network is error prone and errors...
The need for QoS for multimedia traffic arouse from the fact that the current network is a best effort network where all packets are treated equally irrespective of their importance. Moreover when a video packet changes its mode of transport from wired to wireless there arises a need to identify these packets and provide them with prioritized service to achieve end-to-end QoS. In this paper we used...
