information from higher network layers may be
utilized for more efficient power management in wireless
networks and energy constrained mobile devices. In
particular, we present and evaluate mechanisms that finetune
transmission power according to information received
from the transport (feedback reports from TFRC) and
application (type of the video frame encoded) layers.
Further improvements may be applied if the video encoding
is done using capabilities of the SVC standard. We also
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 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. The
mechanisms proposed, offer significant improvements when
used in terms of both power consumption and received
video quality. All proposals are compared and evaluated
using simulation.1 aBouras, Christos1 aStamos, Kostas1 aZaoudis, Giannis1 aStroumpis, Stamatis1 aCharalambides, Savvas  uhttp://telematics.upatras.gr/telematics/publications/power-management-mechanism-exploring-network-and-video-information-over-wireless-links?language=el
