Delay-quality tradeoff for video streaming over MANET using network coding (DQNC)

Although, it was shown that NC is a promising technique to improve the throughput; especially for multicast environment; it also bears negative side-effects (e.g., high decoding delay). Since streaming video are usually subject to strict delay constraints, high decoding delay must be resolved to enhance the performance of the NC schemes. To overcome this issue, this paper presents a new scheme named as Quality-Delay Tradeoff for video streaming over MANET using Network Coding and denoted as DQNC. This scheme operates into two major steps: (i) the first one is processed at the source node and (ii) the second one is treated by the intermediate node that can be considered as a receiver. In comparison with our previous works (i.e, [22] [23]) simulation results show that our new scheme outperforms the existing approaches by improving the video streaming quality and decreasing its decoding delay.
