at each node, determining whether a node can support a requested QoS parameter and admit traffic;

at each node, scouting one or more other available separate channels at different frequencies when the QoS tag values on the first channel fall below a QoS threshold and switching to a second separate channel at a different frequency if QoS tag values on the second separate channel are above the QoS threshold;

at each node, storing the monitored-traffic information in a traffic database;

at each node, processing the monitored-traffic information stored in the traffic database to select one of a reactive, proactive and hybrid route discovery process; and

at each node, discovering traffic routes with the selected route discovery process, each traffic route comprising a combination of wireless communication links.

at each node, selecting discovered routes for communication with other nodes; and

at each node, scouting one or more other available separate channels at different frequencies when the QoS tag values on the first channel fall below a QoS threshold and switching to a second separate channel at a different frequency if QoS tag values on the second separate channel are above the QoS threshold.
