In this paper, we propose a P2P-based content distribution mechanism for video-on-demand service in IPTV. Different from traditional P2P-based content distribution mechanisms, our solution mainly focuses on how telecom operators utilize P2P technology to construct/enhance their own content delivery network for IPTV. The proposed mechanism takes into account the influence on the design of P2P mechanism...
The mobility model of mobile terminals in cellular communication has heavy impact on call admission control (CAC) algorithm. The traditional models have a common defect that a channel is the minimum resource allocation unit which leads to the unsuitability for data communication. However, researches on shared channel in CAC are still lacking. In this article, a general mobility model for cellular...
Multimedia streaming over the Internet has been a very challenging issue due to the dynamic uncertain nature of the channels. This paper proposes an algorithm for the joint design of source rate control and congestion control for video streaming over the Internet. With the incorporation of a virtual network buffer management mechanism (VB), the quality of service (QoS) requirements of the application...
Cross-layer design has been used in streaming video over the wireless channels to optimize the overall system performance. In this paper we extend our previous work (i.e. joint design of source rate control and congestion control for video streaming over the Internet) in P.Zhu et al., (2005) and propose a cross-layer design approach for wireless video streaming. By jointly designing the source rate...
This paper proposes an algorithm for joint design of source rate control and congestion control for video streaming over the Internet. At the application layer, with the incorporation of a virtual network buffer management mechanism (VB), the QoS requirements of the application can be translated into the constraints of the source rate and the send rate. At the transport layer, a QoS-aware congestion...
