Abstract
The main purpose of the proposed multichannel cognitive MAC (MCM) protocol is to improve channel utilization and transmission reliability of safety related data. To achieve the goal, the cognitive radio concept has been adopted within the MCM protocol. The main purpose of the proposed multichannel cognitive MAC (MCM) protocol is to improve channel utilization and transmission reliability of safety related data. To achieve the goal, the cognitive radio concept has been adopted in the MCM protocol. According to the concept of the cognitive radio, primary providers (PPs) are mapped as nodes with safety related data (e.g., emergency vehicles such as police cars, ambulance, re trucks) and secondary providers (SPs) and secondary users (SUs) are mapped as commercial and general automobiles,where as primary users (PUs) can be any node in the system. A new TDMA(Time Division Multiple Access) based MAC protocol called bitmap- assisted efficiency and scalable TDMA based MAC is proposed for adaptive traffic in hierarchical wireless sensor network that can be deployed in smart cities. Device-to-device communication will be an integral part of 5G wireless network Recent advances the wireless communication technologies and the emergence of computationally rich vehicles are pushing vehicular ad hoc network (VANETs) research to the forefront in academic and industry. We outline some of VANET research challenges that still need to enable the ubiquitous deployment and widespread adoption of scalable, reliable, robust and secure VANET architectures, protocol, technologies, etc.
