============================================================================= Second IEEE Workshop on Networking Technologies for Software Defined Radio (SDR) Networks (Held in Conjunction with IEEE SECON 2007) June 18, 2007, San Diego, California, USA http://www.winlab.rutgers.edu/~wenyuan/sdr07/index.htm Wireless systems have historically operated in relatively static frequency bands allocated to a single type of service. This compartmentalization of spectrum offered few incentives for common designs across frequency bands and limited opportunities for dynamic spectrum sharing. More recently, there has been a push to make more spectrum available, and in response there has been significant research towards developing new classes of “cognitive” radios and their associated protocols. Cognitive radios (CRs), or more generally software defined radios (SDRs), can tune their communication stack to take advantage of spectrum opportunities, adapt to a wide variety of radio interference conditions, and employ protocols that allow for collaboration between previously incompatible technologies. Dynamic physical layer adaptation is achieved by scanning available spectrum, selection from a wide range of operating frequencies, rapid adjustment of modulation waveforms and adaptive power co! ntrol. A suitably designed cognitive radio with a software-defined physical layer would be capable of collaborating with neighboring radios to ameliorate interference using higher-layer protocols. These higher layer coordination protocols could range from etiquette mechanisms to fully collaborative multi-hop forwarding. The potential impact of cognitive radios upon both commercial and military wireless communications is great as they cou allow for improved spectrum utilization and improved interoperability between wireless data standards. The workshop builds upon the success of the First IEEE Workshop on Networking Technologies for Software Defined Radio (SDR) Networks. Although the potential for CR/SDR platforms is great, there remains a need for developing, testing, and prototyping the protocols that will allow the CR platforms to achieve their promise. The purpose of this workshop is to facilitate the exchange of cutting-edge research in cognitive radio and software defined radio technologies. The focus of this workshop is to explore the underlying networking and communication protocols needed to facilitate the interconnection of CR/SDR platforms. Since CR/SDR research is taking place across multiple communities, ranging from academic to government to industry, from physical layer to networking to hardware researchers, we intend for this workshop to serve as a forum for cross-pollination and collaboration that will accelerate the deployment and eventual success of CR/SDR platforms.
