Joint path and spectrum diversity in cognitive radio ad-hoc networks

The uncertain availability of the spectral resource imposes unique challenges in cognitive radio networks. One of the critical issues is to counteract the performance degradation experienced by cognitive users (CUs) due to the activity of primary users (PUs). Since the activity of PUs varies both in frequency and space domain, diversity techniques can represent an efficient way to address this ...

Distributed Intelligent Spectrum Management in Cognitive Radio Ad Hoc Networks

The invention of portable hand-held devices, such as smart phones and tablet personal computers (PCs), has led to a dramatic increase in the demand of ubiquitous wireless communication networks and has shaped the way people communicate these days. Ranging from old-fashioned cellular networks (e.g., 4G networks) to recent local area networks (e.g., WiFi networks) or body area networks (e.g., Blu...

Opportunistic Spectrum Access in Cognitive Radio Ad Hoc Networks

Cognitive Radio (CR) technology is envisaged to solve the problems in wireless networks resulting from the limited available spectrum and the inefficiency in the spectrum usage by exploiting the existing wireless spectrum opportunistically. CR networks, equipped with the intrinsic capabilities of the cognitive radio, will provide an ultimate spectrum aware communication paradigm in wireless com...

Learning-Based Spectrum Selection in Cognitive Radio Ad Hoc Networks

Cognitive Radio Ad Hoc Networks (CRAHNs) must identify the best operational characteristics based on the local spectrum availability, reachability with other nodes, choice of spectrum, while maintaining an acceptable end-to-end performance. The distributed nature of the operation forces each node to act autonomously, and yet has a goal of optimizing the overall network performance. These unique...
