dc.description.abstract | Cooperative relay is a promising technique that can improve network capacity in multi-hop wireless networks. However, conventional video streaming schemes on cooperative relay networks do not consider the video complexity of each video sequence. In this paper, we develop and experimentally evaluate a video streaming scheme that considers video complexity over a cooperative multi-hop relay network. We first develop a video distortion model taking into account the video complexity of the video sequences. Then, we propose a flow-routing algorithm for heterogeneous motion-level video streams in multi-hop cooperative networks. To evaluate the video routing performance for heterogeneous motion-level video sequences, we conduct experimental simulations with the proposed routing algorithm and a video distortion model. Numerical results show that network performance improves when video sequences are routed while considering heterogeneous motion levels to maximize the minimum peak signal-to-noise ratio (PSNR) value for the video sessions. The simulation results also show that the adoption of cooperative relays and a hop-count limitation can also improve the routing performance of video streams. (C) 2015 Elsevier B.V.
