One of the most challenging issues facing vehicular networks lies in the design of an
efficient MAC protocol adaptable to different traffic scenarios (urban and suburban …

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

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 …

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 …

Abstract The Wireless Access in Vehicular Environments (WAVE) protocol stack has been
recently defined to enable vehicular communication on the Dedicated Short Range …

This paper introduces a novel framework of coordinated spectrum sensing in cognitive-radio-
enhanced vehicular ad hoc networks (CR-VANETs). The proposed sensing coordination …

With rapid development of wireless technology, the fixed resource allocation strategies that
are utilized in wireless networks to guarantee the Quality of Service lead to the shortage of …

Vehicular ad hoc networks (VANETs) can improve the safety during the traffic by enabling
cooperative communication among the vehicles. The media access control (MAC) protocol …

Vehicular ad hoc networks (VANETs) need to support the timely end-to-end transmissions of
safety and non-safety messages. Medium access control (MAC) protocols can ensure fair …
