Anti-jamming Performance of Hybrid FEC code in the Presence of CRN Random Jammers (original) (raw)

2014

Abstract

The survivability of Cognitive Radio Networks (CRNs) operating in the presence of malicious attackers, especially jammers is a crucial security issue. Cognitive Radio (CR) jammers are capable of taking advantage of the reconfigurable features of CRN so as to cause faults of different severity including value faults. The performance of CRNs under jamming attacks using the hybrid fault-model approach which considers different fault scenarios have been investigated. A hybrid Forward Error Correction (HFEC) code was proposed so as to mitigate the observed high jamming impact of CR jammers. The proposed HFEC code was defined as a concatenation of the Raptor code and the Secure Hash Algorithm-2 (SHA-2). The Raptor part is used to recover data loss due to jamming, while SHA-2 is used to verify the integrity of data received at the destination since CR jammers are capable of manipulating transmitted data leading to value faults. The HFEC code was designed in this manner so as to make it cap...
