Layered video multicast using fractional frequency reuse over wireless relay networks
Nowadays, multimedia services over wireless networks are increasingly popular. With multicast, many mobile stations can join the same video group and share the same radio resource to efficiently increase frequency utilization. However, users may be located at different positions, and so suffer different degrees of path loss and interference, and receive a different signal-to-interference and no...

متن کاملVideo Multicast Over Wireless Ad Hoc Networks
Existing video multicast routing protocols in wireless ad hoc networks have been developed under the assumption that destination nodes wish to receive all the information sent by the multicast source, i.e., they do not support heterogeneous destinations. This paper addresses the problem of video multicast for heterogeneous destinations in wireless ad hoc networks. Multiple Description Coding (M...
متن کاملScalable video multicast using inter-layered superposition and network- coded cooperation over MIMO relay systems
The adoption of scalable video coding (SVC) for video multicast services is a promising solution for providing efficient streaming under channel heterogeneity, since SVC can support quality scalability with high coding efficiency. The scalability allows receivers to experience video quality according to their channel conditions. Nevertheless, the scalable video layers are inter-dependent; if a ...
متن کاملRateless Coding over Wireless Relay Networks Using Amplify/Decode and Forward Relays
In this paper two different rateless transmissionschemes are developed. In the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination. Based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay ...
