Cross-layer architecture for adaptive video multicast streaming over multirate wireless LANs

User-Centric Energy-Efficient Multimedia Multicast/Broadcast Solutions: A Survey

“…The cross-layer adaptive multicast video streaming in [81] considers the application, data link, and physical layers jointly, where a channel-dependent auto rate selection wherein hierarchical video coding is used. In order to combat packet losses over wireless in a multicast scenario, a layered HARQ scheme is proposed in [82], where operating point for the multicast group is selected via Nash bargaining game.…”

Trends and Challenges for Quality of Service and Quality of Experience for Wireless Mesh Networks

“…Recent advances in wireless optimization are attracting researchers and industry to study cross-layer issues for future networks (Chen et al, 2007). Other cross-layer implementations supporting QoS in wireless system, as well as, load balance techniques can be found in (Pahalawatta et al, 2007), (Wu et al, 2007) and (Villalon et al, 2007). It is clear that the cross-layer schemes will be predominant in WMNs, where new quality level mechanisms will be designed and implemented to increase the satisfaction of costumers and optimize the usage of network resources, such as routing protocols.…”

Delivering live-action to handheld devices: Experimental results and recommendations

“…The use of WiFi is attractive to the consumer since there are no additional airtime charges. Support for live and interactive video remains a challenge because the use of Application or MAC layer retransmission produces unacceptable fixed and variable delays [1,2]. Furthermore, to support large numbers of users it is not efficient to use multiple unicast streams.…”
