Emerging Technologies, Applications and Futuristic Scope of Cognitive Vehicular Network for 5G Wireless Systems

Research and study on fifth generation (5G) wireless communication systems is growing at a massive rate and has the potential to provide enhanced quality-of-experience (QoE), high spectral availability, less power utilization and less end-to-end latency to the wireless system designers. New wireless applications demand high data rates and mobility thereby urging for a deep excavation on 5G wireless systems. This article presents a heterogeneous network system based framework for 5G wireless systems. It proposes a potential cellular architecture that discusses various emerging and promising schemes for 5G wireless network such as cognitive radio oriented network, massive multiple-input multiple-output (MIMO), effective and energy-efficient communication systems, and visible light communication. The focus of the proposed prototype is on making the most effective use of quality of service (QoS), energy efficiency and spectral efficiency in heterogeneous wireless network and is expected to facilitate the interpretation of critical technical challenges towards spectrum efficient 5G wireless network.
