Congestion-optimized multi-path streaming of video over ad hoc wireless networks

We analyze the benefits of optimal multi-path routing on video streaming, in a band-limited ad hoc network. In such environments the actions of each node can potentially impact the overall network conditions. Thus optimal routing solutions which seek to minimize congestion are attractive as they make use of the resources efficiently. For low-latency video streaming, we propose to limit the number of routes to overcome the limitations of such solutions. To predict the performance in terms of rate and distortion, we develop a model which captures the impact of quantization and packet loss on the overall video quality. Simulations are performed to illustrate the advantages of the multi-path congestion-based partitioning scheme and confirm the validity of the model.
