In this study, the implementation of a multicast router protocol with a multilayer and multi‐hop consideration on the ad hoc CRN mobile was achieved through the use of a combined expected transmission count metric (ETX) with the Steiner minimal tree (SMT). The conjoined SMT‐ETX multicast CRN channel spectrums, which were used for measuring the availability of channels and the time required for data transmission from a given cognitive radio (CR) source to all of the CR destinations nodes was found to have resulted in the most efficient channel that was largely based on the possibility of success (POS) channel assignment scheme's probability success. Apart from demonstrating the best throughput and packet delivery rate performances for SMT‐ETX multicast CRN with POS scheme than those of the three multicast router protocol (MASA, MDR and RS) schemes with different primary users (PUs) traffic load and network parameters at Rayleigh fading channel, the SMT‐ETX multicast CRN with the decreasing PUs traffic load had also implied a higher chance of achieving the available secondary users channels in the CR network.
