Fully Distributed Cooperative Spectrum Sensing for Cognitive Radio Networks Navarro Arribas, Guillermo Rifà Pous, Helena Garrigues Olivella, Carles Cognitive radio networks (CRN) spectrum radio cognitiva espectro ràdio cognitiva espectre Cognitive radio networks ràdio cognitiva radio cognitiva Cognitive radio networks (CRN) 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 force a wrong decision. Providing security to the sensing process is also complex, as it usually involves introducing limitations to the CRN applications. The most common limitation is the need for a static trusted node that is able to authenticate and merge the reports of all CRN nodes. This paper overcomes this limitation by presenting a protocol that is suitable for fully distributed scenarios, where there is no static trusted node. info:eu-repo/semantics/bookPart 978-84-615-9933-2 Garrigues, C.;Rifà, H.;Navarro-Arribas, G..
