Abstract:
|
Cognitive radio networks sense spectrum occupancy and manage themselves
to operate in unused bands without disturbing licensed users. The detection capability of a
radio system can be enhanced if the sensing process is performed jointly by a group of nodes
so that the effects of wireless fading and shadowing can be minimized. However, taking a
collaborative approach poses new security threats to the system as nodes can report false
sensing data to reach a wrong decision. This paper makes a review of secure cooperative
spectrum sensing in cognitive radio networks. The main objective of these protocols is to
provide an accurate resolution about the availability of some spectrum channels, ensuring the
contribution from incapable users as well as malicious ones is discarded. Issues, advantages
and disadvantages of such protocols are investigated and summarized. |
