Abstract: The layered structure is one of the key reasons behind the success of
the Internet. However, cross-layer design is appropriate and may even
be necessary in wireless networks due to their intrinsic characteristics,
such as limited bandwidth, user mobility and power constraints. Recently,
cross-layer design for wireless multimedia networks has become a hot-topic
in both academia and industry. Cross-layer optimization is a new frontier
in the field of wireless communications, which will result in new algorithms
and significantly improved performance for wireless networks, such as ad hoc
networks, sensor networks, cellular networks, cognitive radio and green
communication networks. In this talk, we consider cross-layer design for
quality of service (QoS) provisioning in wireless networks. Specifically,
we propose novel cross-layer schemes taking into account both physical layer
fading channels and application layer packet multimedia traffic. By considering
the interplay of different layers, we show that the network performance can be
increased significantly. Some implementation considerations of the cross-layer
design schemes will also be presented.
