Abstract: Compared to traditional mobile ad hoc
networks, wireless sensor networks and
infrastructure-based mobile cellular networks,wireless
mesh networks (WMNs) are: (a) quasi-static in network
topology and architecture, (b) not resource constrained
at the mesh routers and (c) are easy and flexible to
deploy. These technological advantages are especially
appealing to the emerging market requirements on future
wireless networks and services. WMNs combine wired and
wireless networks with wireless routers as backbones and
mobile stations as users. Wireless routers communicate
with each other, and conduct multihop communications to
forward mobile wireless stations' traffic to/from wired
networks.
Mobile users' traffic travels over wireless routers and
reaches wired networks. Each mobile station also acts as
a router, forwarding packets for other mobile stations.
As mobility and energy- saving are no longer issues, WMN
routing considers link quality metrics suh as capacity
or error probability. Potential applications of WMNs
include broadband home networking, community and
neighbourhood networking, enterprise networking,
building automation, health and medical systems, public
safety and security systems,intelligent transportation
systems, emergency/disaster networking, metropolitan
area broadband Internet access. This wide range of
applications have different technical requirements and
challenges in the design and deployment of mesh
networking architectures, algorithms and
protocols.Quality of service (QoS) is a challenging
issue in WMNs which promise to support a variety of
traffic types. They should satisfy, for example, the
requirements of video streaming , Web surfing, bursty
traffic over the Internet. In addition, they may need to
deal with all different types of traffic simultaneously.
As a consequence, various QoS classes are defined
according to different traffic types. Users have strong
preference for wireless access, and hence the increase
in wireless access capacity could drive a wave of
innovation that increases the total demand and high
speed wreless access proliferates.
This presentation is organized as follows. Starting from
the fact that the wireless mesh networking is an
emerging technology for future broadband wireless
access, WMNs overview is reported, together with
streaming over mesh networks. Future wireless networking
can benefit from a robust and reliable wireless mesh
backbone rendered by mesh routers providing an all
wireless ambiance. From this point of view, second part
of this work deals with routing in WMNs including
metrics as well as cross-layer design. As wireless mesh
networking is an important architecture for future
generation wireless communication systems, QoS
provisioning as a challenging issue is considered in the
third part. Open research issues and future work
conclude the presentation.
