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 …

The key for cooperative collision avoidance (CCA) systems is the real-time and reliable
delivery of safety-related messages among vehicles, which include periodical beacons and …

In support of traffic safety applications, vehicular networks should offer a robust Medium
Access Control (MAC) layer protocol that can provide a reliable delivery service to safety …

Traditional wireless sensor networks (WSNs) work over the unlicensed spectrum, and as the
spectrum becomes increasingly crowded, they suffer from uncontrolled interference …

We propose a novel dynamic common-control-channel-based medium access control
(DCCC-MAC) protocol for cellular (centralized) cognitive radio (CR) networks. Specifically …

Vehicular Ad hoc NETworks (VANETs), an important part of the Intelligent Transportation
System (ITS), should provide the reliable safety message broadcasts and efficient non-safety …

Recently, machine-to-machine (M2M) communications has become an emerging paradigm
that provides ubiquitous connectivity among numerous devices to support diverse …

With the rising demand for vehicular networking through wireless communication for safety
as well as non-safety applications, the urge to provide efficient bandwidth utilization along …

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) …

Key application of an intelligent transportation system is traffic safety, and it provides driver
assistance. Safety messages are of two types, beacon messages and event messages. The …
