Power Management for SVC Video over Wireless Networks

The main idea of this paper is to study how the emerging H.264 SVC standard can be utilized for more efficient power management in wireless video transmissions. Our proposal uses a cross-layer approach which adapts the power transmission level of the sender according to the SVC information regarding the priority of the SVC NAL frame. Our aim is to improve transmission statistics, and therefore user experience, without unnecessary power consumption. We use extensive experimentation on the ns2 network simulator, which we have specifically modified for this purpose, in order to verify this approach.
