Cloud Radio Access Networks (C-RAN) promise to leverage cloud computing capabilities for enhancing the quality and coverage of next generation 5G networks. 5G networks shall witness an increasing density of users and access points, very small latencies, more bandwidth resources, and the use of virtualized hardware for baseband processing. Within such an environment, the problem of scheduling the network...
This paper investigates the station (STA)-access point (AP) association and airtime control for virtualized 802.11 networks to provide service customization and fairness across multiple Internet service-providers (ISPs) sharing the common physical infrastructure and network capacity. More specifically, an optimization problem is formulated on the STAs' transmission probabilities to maximize the overall...
We conduct cross-layer analysis to demonstrate that impairment-aware scheduling is ineffective in compensating the Q-factor degradation impact on all-optical routers based on arrayed waveguide gratings (AWGs) and fiber delay lines (FDLs).
In this paper, we address the problem of robust network design. Robustness is defined as the minimizing variations in network performance, such as average delay and throughput, due to the perturbations in the network, e.g. topology, demand and community of interest. We pose an optimization problem is cast in the form of minimizing a new robustness metric that is a function of network routing, capacities...
