Rapid broadcast of safety message (sm) is critical for real-time applications in cognitive
radio vehicular ad hoc networks (CR-VANETs). The arrival of primary users (PU) and the …

Recent developments in intelligent transportation system (ITS) require a reliable medium
access control (MAC) protocol to support the high-priority safety message broadcast. The …

Cognitive Radio (CR) is a recent network paradigm that allows Secondary Users (SUs),
such as, wireless devices/users, to intelligently access portions of the radio spectrum not …

Advancements in intelligent transportation necessitate a dependable medium access control
(MAC) protocol to enable high-priority safety broadcasts. Implementing cognitive radio …

This paper proposes a spectRum Aware cRoss-layEr (RARE) medium access control
protocol for cognitive radio ad-hoc networks. The RARE protocol initially splits the network …

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

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 …

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 …
