CALL FOR PAPERS

COMPUTER NETWORKS (Elsevier) Special Issue on

Cognitive Wireless Networks

http://www.elsevier.com/locate/comnet

Rapid advances in key enabling technologies such as high-speed digital signal processing, wideband A/D conversion, smart antennas, low power amplifiers, and reconfigurable hardware will lead to new kinds of Software Defined Radios (SDRs). These combined with new ability to sense the radio environment in real time and make intelligent policy driven decisions will lead to a new form of Cognitive Radio (CR). Recognizing this evolution the FCC and similar regulating bodies world over (e.g., OfCom, UK) have envisioned relaxed spectrum access policies which will fuel the evolution of cognitive radio (CR) and cognitive wireless network (CWN) technologies.

Still nascent in its development, CWN technology promises to alleviate the spectrum scarcity problem resulting from existing command-and-control management of spectrum. The CWNs will allow secondary users to share primary licensed spectrum without harming the primary users. This requires efficient algorithms for rapid detection of primary users and new Medium Access (MAC) protocols. Also, CWNs need to allocate and coordinate spectrum access at various times scales. This requires that the problem of dynamic spectrum allocation (DSA) be addressed in a new light. Building a fully functional CWN with the aforementioned capabilities is one of the foremost challenges facing wireless network designers today. As CWN technology matures, it can transform home networks,cellular networks, wireless LANs and many other applications.

The present special issue is expected to be published in May 2007. It will concentrate on new developments, applications, and challenges that have appeared in the last several years in connection with cognitive radio technology. Topics of this open call include but are not limited to:

• Dynamic spectrum allocation in heterogeneous networks • Novel methods for rapid detection of primary users • Routing in CWN networks • Fundamental (network) limits of CR technology • Impact of MIMO and OFDM techniques on cognitive radio networks • Mesh networking for CR technology • Cross-layer optimization in CR networks • Implementation challenges and limits for CR technology platforms • Legal, social, and regulatory issues for CR networks implementation • Critical ad hoc heterogeneous-content networks (e.g., public safety) • Applications of CR technology: home networks, WLANs, etc.
