In other words, our analysis assumes the existence of
multiple orthogonal channels for transmission. In practice, however, interference effects in
wireless networks can severely degrade the throughput. Consequently, particularly in a
multi-user scenario, resource management and routing become of paramount importance
for minimizing interference. In [37], a rate matrix was introduced to describe the state of
the network at a given time. In [7], an elementary capacity graph was used to represent the
physical layer state of the various links. In [38], a node-link incidence matrix was used.
More details about wireless video transmission with interference consideration can be
found in [32].
5.8 Conclusions
Delay-constrained video streaming over multi-hop wireless mesh networks is an
application that deserves considerable attention due to the research challenges imposed by
such a service, as well as due to the important role that robust and efficient multimedia
services have when it comes to commercial deployment of such networks in office and
residential areas. We investigated a framework where QoS guarantees are provided for
video transmission over a variety of links in a multi-hop network using IEEE 802.
