Power Management Adaptation Techniques For Video Transmission Over TFRC

In this paper, we describe power management adaptation techniques for wireless video transmission using the TFRC protocol that take into account feedback about the received video quality and try to intelligently adapt transmitting power accordingly. The purpose of the mechanisms is to utilize TFRC feedback and thus achieve a beneficial balance between the power consumption and the received video quality. There are 2 power adaptation mechanisms proposed, each one with its own advantages. They both offer significant improvements when used in terms of both power consumption and received video quality. We use simulation in order to compare and evaluate our approach.
