The prediction-based routing in optical transport networks
In optical networks, the traditional routing problem is generally decoupled into two subproblems, the route selection and the wavelength assignment. Usual RWA (Routing and Wavelen...

Scheduling in Mobile Ad Hoc Networks with Topology and Channel-State Uncertainty
—We study throughput-optimal scheduling/routing over mobile ad-hoc networks with time-varying (fading) channels. Traditional back-pressure algorithms (based on the work by Tassiu...
