Futuristic device-to-device communication paradigm in vehicular ad-hoc network

Emerging heterogeneous networking is designed to accommodate large volumes of data traffic especially in vehicular environment. As a result, an increased level of QoS requirements and new solutions to ensure fast and reliable data delivery has become indispensable. In this context, device-to-device (D2D) communication technology in 5G network provides a reliable infrastructure which will enable dissemination of various safety and non-safety applications. D2D communication alleviates fast communication between vehicles thereby improving the spectral efficiency, system capacity and throughput and overall performance of the system. This paper develops a paradigm to extend D2D for vehicular infrastructure with the capacity to facilitate vehicular traffic using the LTE band. To analyze the proposed scheme performance, simulations based on LTE network are performed. Results show that our approach provides significant enhancement over IEEE 802.11p standard and LTE-A technology in terms of different performance metrics.
