Scattered Spectrum Sensing in Cognitive Radio Network

Spectrum sensing is a key enabling functionality in Cognitive Radio (CR) networks, where the CRs act as secondary users that opportunistically access free frequency bands. Scattered Spectrum Sensing (SSS) enables a Cognitive Radio (CR) network to reliably detect licensed users and avoid causing interference to licensed communications. The data fusion technique is a key component of SSS. Byzantine failure problem with respect to data fusion is discussed, which may be caused by either malfunctioning sensing terminals or Spectrum Sensing Statistics Erroneous attacks (SSSE).
