Multi-Radio Channel Detecting Jamming Attack Against Enhanced Jump-Stay Based Rendezvous in Cognitive Radio Networks

Rendezvous problem has been attracting much attention as a fundamental process to construct the Cognitive Radio Network (CRN). Many elegant algorithms have been proposed to achieve rendezvous on some common channel in a short time, but they are vulnerable to the jamming attacks where a jammer may exist listening or blocking the channels [13]. In this paper, we propose the Multi-Radio Channel Detecting Jamming Attack (MRCDJA) problem where the jammer can access multiple channels simultaneously. We assume the users adopting the Enhanced Jump Stay (EJS) [7] algorithm, which guarantees rendezvous by generating a channel hopping sequence, and our goal is to determine the hopping sequence as quickly as possible.
