On Detecting Termination in Cognitive Radio Networks [PDF]
2011 IEEE 17th Pacific Rim International Symposium on Dependable Computing, 2011 SUMMARYThe cognitive radio networks are an emerging wireless communication and computing paradigm. The cognitive radio nodes execute computations on multiple heterogeneous channels in the absence of licensed users (a.k.a. primary users) of those bands. The termination detection is a fundamental and non‐trivial problem in distributed systems.

2012 9th International Conference on Communications (COMM), 2012 Cognitive Radio Networks (CRNs) are emerging as a solution to increase the spectrum utilization by using unused or less used spectrum in radio environments. The basic idea is to allow unlicensed users access to licensed spectrum, under the condition that the interference perceived by the licensed users is minimal.
