Abstract
Proceedings of: 2010 IEEE Global Telecommunications Conference (GLOBECOM 2010), 6-10 December 2010, Miami, Florida, USAWireless communication technologies such as microwave radios are used to provide high-speed mobile backhaul
connectivity for radio access networks in cases in which wirebased
alternatives, e.g. cable or fiber, are not readily available
and cannot be deployed in an economic or timely manner.
Current mobile backhauls are predominantly deployed in tree
or ring topologies, which simplify traffic management. Yet, with
the increasing demand on backhaul capacity and the immense
cost pressure on mobile backhaul solutions, meshed wireless
mobile backhauls have been identified as a promising evolution.
While traffic management in wireless mesh networks have been
studied extensively in the literature, so far there is no quantitative
analysis comparing the different topology options, i.e. mesh, ring
and tree, regarding network performance and deployment cost.
This paper fills this gap by studying the minimum cost problem
of connecting a set of base station/gateway sites using different
topologies while supporting both time- and space-varying traffic
demands. Furthermore, we consider the additional constraint
of resilience to single link failures. The evaluation results show
that meshed wireless backhaul topologies are a cost-effective
alternative to trees and rings, in particular in the face of spatial
and temporal fluctuation of traffic demand and protection against
link failuresEuropean Community's Seventh Framework ProgramPublicad
