TLDR
In this paper, the authors proposed video-aware opportunistic network coding schemes that take into account both aspects, namely (i) the decodability of network codes by several receivers and (ii) the distortion values and playout deadlines of video packets.Abstract:
In this paper, we study video streaming over wireless networks with network coding capabilities. We build upon recent work, which demonstrated that network coding can increase throughput over a broadcast medium, by mixing packets from different flows into a single packet, thus increasing the information content per transmission. Our key insight is that, when the transmitted flows are video streams, network codes should be selected so as to maximize not only the network throughput but also the video quality. We propose video-aware opportunistic network coding schemes that take into account both aspects, namely (i) the decodability of network codes by several receivers and (ii) the distortion values and playout deadlines of video packets. Simulation results show that our schemes significantly improve both video quality and throughput.read more

Method for Network Coding Packets in Content-Centric Networking Based Networks
TL;DR: In this paper, a network node, comprising a data store comprising multiple content chunks, a receiver configured to receive a request from a requesting network node for at least one chunk of the content object, a transmitter configured to transmit data, and a processor coupled to the receiver, the transmitter, and the data store, is configured to encode the content using the multiple contents.

Video-aware opportunistic network coding over wireless networks
TL;DR: This work proposes video-aware opportunistic network coding schemes that take into account both the decodability of network codes by several receivers and the importance and deadlines of video packets, and shows that these schemes significantly improve both video quality and throughput.

Network information flow
TL;DR: This work reveals that it is in general not optimal to regard the information to be multicast as a "fluid" which can simply be routed or replicated, and by employing coding at the nodes, which the work refers to as network coding, bandwidth can in general be saved.

Linear network coding
TL;DR: This work forms this multicast problem and proves that linear coding suffices to achieve the optimum, which is the max-flow from the source to each receiving node.
