Abstract:

This final report is divided into two parts. In the first part, we present the generalization of our joint source-network coding scheme FGA-FEC to wireless video communications. We consider the in-net adaptation of video resolution, frame-rate, and quality to match the network link parameters of bandwidth, packet-loss probability, and bit-error rate, as well as the specific requestsneeds of the end-users. This algorithm assumes a high-rate network backbone that is relatively lossless. In the second part of this report, we extend this FGA-FEC method to work in a distributed fashion on internal network nodes, thus making it suitable for peer-to-peer networks. We assume the nodes possess some computational ability in addition to forwarding and routing capability, not unlike a PC.
