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) …

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

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

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 …

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 …

This paper presents a novel medium access control medium access control (MAC) for
distributed single-channel cognitive radio networks (CRNs) denominated cognitive radio …

Cognitive radio technology can improve spectrum efficiency by allowing secondary users to
opportunistically access frequency bands. Although a number of approaches have been …

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 …
