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=el01168nas a2200157   4500008004100000245005800041210005800099300001500157520060800172100002100780700001900801700002100820700002400841700002600865856011900891       2011                        eng d00aPower management for SVC video over wireless networks0 aPower management for SVC video over wireless networks  a 270 - 2763 aThe 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.1 aBouras, Christos1 aStamos, Kostas1 aZaoudis, Giannis1 aStroumpis, Stamatis1 aCharalambides, Savvas  uhttp://telematics.upatras.gr/telematics/publications/power-management-svc-video-over-wireless-networks?language=el01290nas a2200145   4500008004100000245007400041210006900115300001300184520072700197100002100924700001900945700002100964700002400985856013501009       2011                        eng d00aUtilizing Video Enconding for Power Management over Wireless Networks0 aUtilizing Video Enconding for Power Management over Wireless Net  a 57 - 623 aPower management is especially important in wireless networks because of the emergence of energy
constrained mobile devices. This paper examines the ways that video encoding information can be used for
more efficient power management. In particular, we propose and evaluate cross layer mechanisms that fine-
tune transmission power depending on the video frame being encoded and we examine how this mechanism
may be combined with algorithms that adjust transmission power based on feedback reports when TFRC is
used as the transport protocol. Since typical video encoding uses frames of varying importance for the
overall quality, this approach can improve received video quality and make better usage of available power.
