This paper evaluates the applicability to WMNs of dynamic backpressure routing strategies, which theoretically maximize throughput but can result in high end-to-end delays. The authors present a distributed and (quasi-)stateless routing protocol called DiPUMP (forwarDIng of Packets for distribUted resource consuMPtion). Unlike the theoretical form of the backpressure algorithm, DiPUMP does not require a centralized entity computing the routes for the whole network at any instant. Therefore, its distributed operation enables its implementation and deployment in practical WMNs.
