Real-Time Multiple Description Video Streaming over QoS-Based Wireless Networks

We consider the problem of robust video streaming over networks that support QoS differentiation, such as the 802.11e wireless network infrastructure. We consider the benefits obtained matching the H.264 data partitioning (DP) mode with such a QoS-based interface. We compare this solution with an innovative scheme which combines a multiple description (MD) coding framework with a QoS-based network. Results are reported using both a simple IID channel model and a more realistic wireless network, simulated using the OmNet++ network simulator.
