Abstract
Cognitive Radio (CR) is a promising technique to enhance the spectrum utilisation by enabling the CR users to opportunistic access the spectrum holes or channels. To exchange spectrum information most of the existing research have utilised a Common Control Channel (CCC). This results channel saturation, extreme transmission overhead of control information, and a point of vulnerability. To address this problem, Channel Hopping (CH) protocols have proposed for enabling Rendezvous (RDV). This paper presents a CH protocol based on clique system, called clique based channel hopping (CCH) for the purpose of RDV establishment. The proposed CCH is a role based blind RDV CH system where sender and receiver generates CH sequence based on h-clique and v-clique respectively. The CCH protocol satisfies the following requirements: (i) guaranteed RDV; (ii) no synchronisation; and (iii) symmetric and asymmetric channel model. Simulation results show that the proposed clique based channel hopping (CCH) scheme outperforms similar CH schemes in terms of average time-to-rendezvous (ATTR) and the degree of overlap in both symmetric and asymmetric channel scenario.
