An Opportunistic Scheduling Scheme with Minimum Data-Rate Guarantees for OFDMA
Abstract—We tackle the problem of providing minimum datarate guarantees for different classes-of-service in an OFDMAbased network, while obtaining a high system throughput. Our a...

ROAR: A Multi-rate Opportunistic AODV Routing Protocol for Wireless Ad-Hoc Networks
In this paper, we outline a simple approach, called ROAR, that enables the Ad-Hoc On-Demand Distance Vector (AODV) routing protocol to strengthen its routes by recruiting neighbors...

Low complexity resource allocation with opportunistic feedback over downlink OFDMA networks
Abstract--Optimal tone allocation in downlink OFDMA networks is a non-convex NP-hard problem that requires extensive feedback for channel information. In this paper, two constantco...

Utilization and fairness in spectrum assignment for opportunistic spectrum access
The Open Spectrum approach to spectrum access can achieve near-optimal utilization by allowing devices to sense and utilize available spectrum opportunistically. However, a naive d...
