An Efficient Sequence Based Receiver Initiated Multi-Channel Medium Access Control Protocol for Cognitive Radio Network

According to the Federal Communications Commission (FCC), the spectrum utilization has been increasing in a rapid manner. In order to overcome the shortage of spectrum that caused by increased network capacity and the mobile services needed to carry over the spectrum, CRN has been introduced for accomplishing the temporary wireless communication tasks. In CRN secondary users can operate the idle channels those are not engaged by the primary users. Therefore, in CRN for utilizing those idle channels Medium Access Control (MAC) protocols faces some challenges, such as spectrum sensing, spectrum sharing, spectrum management, spectrum mobility, maximize throughput, maximize data transmission and minimize channel rendezvous time. In general, neighbor discovery and channel rendezvous is the main challenge in CRN. To overcome these types of issues, many protocols have been proposed for CRN. However, these protocols are short-off to provide efficient channel rendezvous in many scenarios. In this paper, we have come up with an Efficient Sequence Based Receiver Initiated MAC named as SB-RIM for CRN using Latin Square Sequence Based Technique. This new approach allows the secondary users in CRN to discover neighbor(s), share spectrum and access the available channel(s). Finally, we have evaluated and implemented through simulation and it provides better performance in terms of number of iteration and different performance metrics.
