Wireless mesh networks are being widely deployed around the world as a mean to provide low-cost access to the Internet. The high capacity at mesh routers nodes allows applications such as real time multicast over WMNs. In light of the slow development of IP multicast and the rise of peer-to-peer communication, implementing multicast capability at the application layer is imminent. QoS support for...
Bandwidth management in 802.11 wireless networks is becoming the main issue that should be overcome for IP multimedia services delivery such as IPTV, VoD, VoIP, etc. In this paper, we propose an adaptive bandwidth allocation based on adaptive transmission opportunity to overcome the guaranteed bandwidth issue. This scheme allows the video stream to take up the 802.11 channel proportionally to its...
Since most wireless local area networks (WLANs) eventually access a wired backbone network, there is a need to ensure end-to-end quality of service (QoS) in order to support multimedia traffic in WLAN-wired networks. The implementation of QoS at the media access control (MAC) layer in the WLAN, and IP layer in the wired network presents a challenge in enabling seamless and consistent service differentiation...
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
