Abstract: Rendezvousing the transmissions and radio frequencies is a crucial objective to achieve optimal utilisation of the spectrum bands by secondary users in cognitive radio networks. Many dimensions of research, such as attaining quality of service during transmissions occurring through spectrum bands, optimising security factors to enable fair and trusted transmissions over spectrum bands is happening in the recent past. However, optimising the spectrum band utilisation by rendezvousing the transmissions and radio frequencies of spectrum band as transmission channels is essential against the massive transmissions (flash crowd) framed by multiple users. Concerning this, a batch processing approach called 'clusters-based rendezvousing approach for scheduling the flash crowd transmissions over cognitive radio networks' has proposed in this manuscript. A new distance measuring technique has adapted to perform a clustering process, which has applied on both buffered transmissions and idle radio frequencies. The results obtained from an experimental study indicating the comparatively better performance from the proposed model and, if utilised within the definitive frameworks, can yield better performance results.
