This paper proposes a cluster-based distributed medium access control (CDMAC) protocol
for multichannel and multihop mobile cognitive radio ad hoc networks (CRAHNs) …

In this paper, we propose a distributed multichannel (DMMAC) protocol for multichannel
cognitive radio ad hoc networks (CRAHNs). We compare DMMAC with other previous …

The cognitive radio (CR) technology is an efficient approach to share the spectrum. But how
to access the idle channels effectively is a challenging problem. To solve this problem, we …

This paper proposes a cross-layer based cognitive radio multichannel medium access
control (MAC) protocol with TDMA, which integrate the spectrum sensing at physical (PHY) …

Cognitive radio (CR) technology will empower wireless devices with the capabilities to
dynamically exploit opportunities in both licensed and unlicensed spectra. Thus, the …

Cognitive radio ad hoc networks (CRAHNs) consist of autonomous nodes that operate in ad
hoc mode and aim at efficient utilization of spectrum resources. Usually, the cognitive nodes …

Spectrum for wireless communications is traditionally assigned by inefficient spectrum
access schemes. Portions of the spectrum are exclusively used by specific wireless systems …

This paper proposes a novel medium access control (MAC) scheme for multichannel
cognitive radio (CR) ad hoc networks, which achieves high throughput of CR system while …

Design of an efficient medium access control protocol is critical for proper functioning of a
distributed cognitive radio network and better utilization of the channels not being used by …

The MAC protocol for a cognitive radio network should allow access to unused spectrum
holes without (or with minimal) interference to incumbent system devices. To achieve this …
