CRNet 2010

The 2nd International ICST Workshop on Cognitive Radio Network

August 25, 2010 - Beijing, China

The 2nd International ICST Workshop on Cognitive Radio Network (CRNet 2010) will be held in conjunction with CHINACOM 2010 in Beijing, China, August 25-27, 2010. Accepted and presented papers will be included in the conference Proceedings and IEEE Xplore. High quality accepted and presented papers will be indexed by EI. (pending)

Cognitive radio is an emerging technology in wireless access, aimed at vastly improving the way radio spectrum is utilized. CRNet 2010 is devoted to the development of cognitive radio-based transmission and networking technologies in wireless communications. The workshop provides a forum for discussion of all these developments among engineers, scientists and researchers. The attribution of cognition in the wireless world is one of the most exciting areas in modern telecommunications. As an emerging technology in wireless access, cognitive radio is aimed at vastly improving the way radio spectrum is utilized. The motivation for cognitive radio stems from various measurements of spectrum utilization, which generally show that spectrum is under-utilized. This means that there are many "holes" in the radio spectrum that could be exploited by the secondary users. The secondary user must exploit these spectrum opportunities without causing harmful degradation to the primary system. The research challenges in this area include devising methods for efficient spectrum pooling and sensing, for capacity-approaching transmission scheme, for interference management and dynamic resource allocation, and for cross-layer design of protocols, as well as circuits and architectures meeting the often challenging requirements.
