System and method to provide differentiated routing in multi-hop multi-radio wireless networks
First Claim
Patent Images
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.

Abstract
A method provides for differentiating usage permissions between different categories of communication traffic within a given network. The method includes ensuring one or more categories of traffic never transits communication radios, link, and/or spectrums dedicated to a different category of traffic. A combined routing metric is calculated using a scaling factor for discouraging usage of restricted communication links and encouraging usage of non-restricted communication links.
