Spectrum Sensing Data Falsification Attack in Cognitive Radio Networks: An Analytical Model for Evaluation and Mitigation of Performance Degradation
Cognitive Radio (CR) networks enable dynamic spectrum access and can significantly improve spectral efficiency. Cooperative Spectrum Sensing (CSS) exploits the spatial diversity between CR users to increase sensing accuracy. However, in a realistic scenario, the trustworthy of CSS is vulnerable to Spectrum Sensing Data Falsification (SSDF) attack. In an SSDF attack, some malicious CR users deli...
متن کاملSpectrum Sensing in Cognitive Radio
In modern wireless communications the spectrum is allocated to fixed licensed users and on the other side the number of wireless devices are increasing rapidly, that has lead to spectrum crunch. As the spectrum is precious it has to be utilized efficiently. The solution to mitigate this problem is Spectrum Sharing. One of the innovative approach to recognize and access the spectrum holes presen...
متن کاملSpectrum Sensing in Cognitive Radio
With the fast readying of latest wireless devices , the last decade has witnessed a growing demand for spectrum. However, the exploit spectrum assignment policy becomes a bottleneck for additional economical spectrum utilization, below that an excellent portion of the authorised spectrum is severely under-utilized. The inefficient usage of the restricted spectrum resources urges the spectrum re...
متن کاملIntelligent Algorithms for Spectrum Sensing in Cognitive Radio
Frequency spectrum is scared resource and efficient use of it can easily fulfil the need of future applications. But its efficient use is not possible within the existing system, where the allocation of spectrum is done based on fixed spectrum access policy that causes under use of spectrum. For efficient utilization of spectrum new inventive techniques are needed. Using Dynamic spectrum access...
متن کاملCognitive radio CDMA networking with spectrum sensing
In this paper, the performance of cognitive radio (CR) code division multiple access (CDMA) systems is analyzed. More precisely, CR users belong to a cognitive radio network (CRN), which coexists with a primary radio network (PRN). Both CRN and PRN are CDMA-based, with colocated base stations. Soft hand off and power control are considered in both the CRN and the PRN. Upon the development of an...
