 Application-oriented Multimedia Scheduling Over Lossy Wireless Networks Ödevi
|
|
The emerging wireless networking technologies such as
3G, 4G, and IEEE 802.11a offer orders-of-magnitude higher
throughput, ranging from a few hundred kilobits per second
to about 54Mbps, thus making it feasible to support real-time
video and audio multimedia applications. To function properly,
real-time multimedia applications require effective network
quality of service (QoS) support in terms of throughput,
delay, jitter and loss ratio. To provide network QoS, researchers
have proposed various packet scheduling algorithms,
notably through wireless fair queuing (see [6][7][8][9][10] for
a few examples). These wireless fair scheduling proposals seek
to provide packet-level throughput and delay bounds over the
error-prone wireless channel.
While the performance benefit in terms of network QoS has
been convincingly demonstrated by each of these earlier proposals
[6][7][8][9][10], what is missing is how well such network
performance gain can be translated into the application
domain. Therefore, in this work, we seek a better understanding
of the relation that exists between the better network service
provided by wireless packet scheduling and the actual benefits
as perceived by the applications that use them. Since this is obviously
a broad topic with possibly as many different answers
as there are applications, we narrow our study to three specific
multimedia applications, i.e., MPEG-4 streaming video, H.263
streaming video, and real-time audio. We are interested in evaluating
the performance of wireless fair scheduling algorithms,
under various realistic wireless channel conditions, from the
multimedia application’s perspective.
We make two contributions in this work:
