Traditional Ad Hoc network wireless communication in the past years have
contributed tremendously to the dawn of wireless mesh networks (WMNs)
which have so far been able to provide a significant improvement in capacity
and scalability. Routing metrics which form the basic element for the
routing protocol in this innovative communication technology is a call for
concern as they must take into consideration the wireless medium network
characteristics in order to provide a optimum appreciable QoS performance.
In the past many single-radio routing metrics have been proposed for Ad
Hoc networks which are not compatible with the multi-radio routing scenario
demanded by WMNs. In our work, we provide a comparative analysis
of most recently proposed multi-radio routing metrics for WMNs. We begin
by providing an overview of the features of a wireless mesh network thereby
presenting a better understanding of some of the research challenges of
WMNs. Also, since single-radio routing forms the basis of multi-radio routing,
we in this regard provide a review of some single-radio routing metrics.
In our comparative analysis, an overview of routing protocols for WMNs
is provided enabling an understanding of the demands to be included in a
routing metric to ensure efficient routing in WMNs since different routing
protocols may impose different demands; we then identify the requirements
of multi-radio routing metrics from which we base our comparative analysis.
