1. A method of differentiated routing in a multi-hop multi-radio wireless network, the method comprising: for each of a plurality of communication links, identifying a link type of the communication link as one of-a restricted link and an ANY link; restricting traffic on the restricted links to a particular category of traffic; allowing all traffic on the ANY links including the particular category of traffic; selecting a route for communication between a source node and a destination node by: calculating a combined route metric for each of a plurality of routes between the source node and the destination node, wherein the combined route metric calculation includes a scaling factor for increasing a route metric of each of the restricted links; and selecting the route with the lowest combined route metric.
