Abstract
The visibility and success ofWireless Mesh Network (WMN)
deployments has raised interest among commercial operators in this technology.
Compared to traditional operator access networks WMNs have
the potential to offer easier deployment and flexible self-reconfiguration
at lower costs. A WMN-type architecture considered as an alternative
for an operator access network must meet similar requirements such as
high availability and guaranteed QoS in order to support triple-play content
provisioning. In this paper we introduce an architecture of such a
Carrier-grade Wireless Mesh Access Network (CG-WMAN). We then
present our contribution, an approach to seamlessly integrate unidirectional
broadcast cells (i.e. DVB-T) into such a CG-WMAN. This allows
higher layer protocols to utilize broadcast cells like regular mesh links,
where beneficial for a given payload and receiver distribution. We then
present a typical use case and discuss for which combinations of traffic
type, user distribution and QoS requirements the use of longer range
broadcast technologies can help to improve the overall CG-WMAN performance
in terms of throughput and reliability.
