Advances in Cognitive Radio Ad Hoc Networks

Call for Papers

Cognitive radio (CR) is envisaged as an enabling technology to overcome the problem of spectrum scarcity and inefficient usage by opportunistically using portions of the wireless spectrum. CR networks, equipped with the intrinsic capabilities of cognitive radio, will provide an ultimate spectrum-aware communication paradigm in wireless communications. CR networks, however, impose unique challenges due to the high fluctuation in the available spectrum as well as diverse quality-of-service (QoS) requirements. In particular, in cognitive radio ad hoc networks (CRAHNs), the distributed multihop architecture, the dynamic network topology, and the time- and location-varying spectrum availability are some of the key distinguishing factors that raise unique issues in the network design.

The objective of this special issue is to bring together state of-the-art research contributions that address all aspects of CRAHNs. Original papers describing completed and unpublished work not currently under review by any other journal/magazine/conference are solicited. Potential topics include, but are not limited to:

• Capacity analysis and bounds for distributed CRAHNs
• New theories, architectures, or models for wireless cognitive networks
• End-to-end quality of service guarantees in CRAHNs
• Spectrum sensing and management for CRAHNs
• Cognitive medium access control and scheduling
• Transport layer design, TCP extensions for CRAHNs
• Joint route and spectrum allocation
• Application scenarios and emerging markets over CRAHNs, such as environmental monitoring, smart grids, emergency responders, disaster recovery, high bandwidth multimedia communication, military deployment, and homeland security among others
• Cooperation in CRAHNs
• Optimized resource management and adaptive cross-layer design
• Security challenges in CRAHNs
• Game theory, economics of deployment, and machine learning
• Experimental and testbed-based studies
• Standards development for CRAHNs
• Challenges and application limits faced by CRAHNs
• Performance evaluation studies
