Backpressure Routing is a cross-layer control algorithm that makes decisions on routing and resource allocation in mobile ad hoc networks using network state information like queue backlog values and current available channel rates. While it is desirable because of its provable performance guarantees, including providing optimal throughput, the real world problem of implementing backpressure routing...
In this paper, a cross-layer optimal scheduling algorithm for cooperative multi-hop Cognitive Radio Networks (CRNs) is presented, where secondary users (SUs) assist primary users' (PUs') multi-hop transmissions and in return gain an immediate time-share of the channel proportional to their assistance. While providing deterministic upper-bounds for PU queue backlogs, the proposed algorithm approaches...
This paper considers the joint routing and scheduling problem in wireless networks with lossy channels. In order to combat channel loss, packets are assumed to be transmitted by nodes using broadcast, instead of traditional point-to-point communication. We first analyze the network capacity region, and then propose a back-pressure routing with max-weight scheduling algorithm to achieve it. The proposed...
