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 …

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 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 …

Cognitive radio ad hoc networks (CRAHNs) have recently been proposed as a way to bring
cognitive radio (CR) technology to traditional ad hoc networks. An important problem is to …

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

The MAC protocol of a cognitive radio (CR) device should allow it to access unused or under-
utilized spectrum without (or with minimal) interference to primary users dynamically. To …

MAC protocol design for cognitive radio (CR) should provide access control for unused
spectrum without or with minimal interference to primary users. On this basis, considering …

Cognitive radio ad hoc networks (CRAHNs) have recently been proposed as a way to bring
cognitive radio technology to traditional ad hoc networks. An important problem is to design …

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) …
