Power Management for SVC Video Over Wireless Networks

Free registration required

Executive Summary

This paper is to study how the emerging H.264 SVC standard can be utilized for more efficient power management in wireless video transmissions. The authors' 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. Their aim is to improve transmission statistics, and therefore user experience, without unnecessary power consumption. They use extensive experimentation on the ns2 network simulator, which they have specifically modified for this purpose, in order to verify this approach.
