Spectrum Monitoring during Reception in Dynamic Spectrum Access Cognitive Radio Networks

IEEE CTN Issue: March 2012
If a frequency band has primary and secondary users, then the cognitive radios of the secondary users must monitor the band and cease to transmit if a primary user's radio begins to transmit. Traditional methods require the secondary users to not transmit while they monitor for the emergence of primary user signals. This article proposes and analyzes techniques by which the secondary radios can continue transmitting during monitoring. IEEE Transactions on Communications

A survey on facilities for experimental internet of things research

IEEE CTN Issue: February 2012
The proliferation of an enlarged gamut of devices able to be directly connected to the Internet is leading to a new ubiquitous-computing paradigm. Indeed, the Internet has experienced a tremendous growth in the past three decades, evolving from a network of a few hundred hosts to a platform capable linking billions of “things” globally, including individual people as well as enterprises of various sizes, through computers and computerized devices of any conceivable size and capability and the applications running on them.

NGSON: Features, State of the Art, and Realization

IEEE CTN Issue: February 2012
The rapid deployment and expansion of the Internet has created both an opportunity as well as a challenge in terms of service delivery. The opportunity comes from the variety and global scale of value added applications that can be supported for users. The challenge comes from the difficulties of developing and deploying software to support these applications and users. Service Oriented Architecture (SOA) and Service Delivery Platform (SDP) were introduced to help with these issues, but lacked support for service delivery and QoS across different domains.
