An Opportunistic Spectrum Scheduling Scheme for Multi-Channel Cognitive Radio Networks
—In this paper, we develop an opportunistic spectrum scheduling scheme for cognitive radio networks. In the proposed scheme, the channel status (i.e., whether being occupied by p...

Probabilistic Path Selection in Opportunistic Cognitive Radio Networks
Abstract—We present a novel routing approach for multichannel cognitive radio networks (CRNs). Our approach is based on probabilistically estimating the available capacity of eve...

Optimal Competitive Algorithms for Opportunistic Spectrum Access
We consider opportunistic spectrum access (OSA) strategies for a transmitter in a multichannel wireless system, where a channel may or may not be available and the transmitter must...
