Vehicle to Vehicle Communication Using Cognitive Radio Technology

Computer Engineering

Vehicle-to-vehicle (V2V) communication is pivotal for enhancing road safety and traffic efficiency in modern transportation systems. However, traditional V2V systems encounter significant challenges, including spectrum scarcity and interference issues, which hinder their effectiveness. Cognitive radio technology emerges as a promising solution tomitigate these challenges by enabling vehicles to intelligently sense and utilize available spectrum bands opportunistically. This paper offers a comprehensive overview of V2V communication leveraging cognitive radio technology, delving into fundamental principles, system architectures, communication protocols, and diverse applications. We examine the transformative potential of cognitive radio in V2V communication, highlighting its advantages such as dynamic spectrum access and interference mitigation capabilities. Furthermore, we explore the implications of cognitive radio technology on various V2V applications, including collision avoidance, cooperative driving, and traffic management, emphasizing its role in fostering safer and more efficient transportation networks. Despite its promises, the deployment of cognitive radio based V2V systems presents challenges such as spectrum sensing in dynamic vehicular environments and regulatory compliance. We advocate for future research endeavours aimed at addressing these challenges and advancing cognitive radio technology to realize the full potential of V2V communication, ultimately contributing to the development of safer and more efficient transportation ecosystems.
