… in the levels of situation awareness and cognitive functionality. Such diverse expectations
make performance evaluation a great challenge in the design of CR devices and networks. …

… Related work and motivation for application of NNs to cognitive radio systems are presented
in Section 3. Performance evaluation scenarios and results are presented and discussed in …

… of Spectrum Sensing Techniques for Cognitive Radio Networks Abstract- Cognitive radio is
… Spectrum sensing is one of the most important functions in cognitive radio (CR) applications. …

… of the radio spectrum. A cognitive radio system is able to sense its functional and
geographical surrounding and adjust its operation. Therefore, cognitive radio operation has to be …

This paper studies cooperative spectrum sensing in cognitive radio networks where secondary
users collect local energy statistics and report their findings to a secondary base station, …

With the implementation of channel assembling (CA) techniques, higher data rate can be
achieved for secondary users in multi-channel cognitive radio networks. Recent studies which …

Since a cognitive radio does not have fixed spectra, it may need to sense a very large frequency
range to find an available band. The sensed aggregate bandwidth could be as large as …

… In this paper, we have proposed a cognitive radio approach … the performance of IEEE
802.15.4 based MBAN radios. The measurement results show that the performance of the radio for …

… Secondly, through performance evaluation, we demonstrate the benefits of REM-enabled
cognitive spectrum-sharing networks in refarming previously licensed bands, eg, the TV …

… In this paper, we addressed performance evaluation of TCP over Cognitive Radio Ad Hoc
Networks (CRAHNs). To this aim, we presented an extension of the NS-2 tool for the modeling …
