The next-generation wireless network has to handle a large amount of data transmission resources which need study on new technologies like machine2 machine communication, device 2 device communication etc., the integration of social network and device 2 device communication in 5G and upcoming 6G networks poses very important challenges in various QoS parameter. This paves way for improvement of spectral and energy efficiency for a vehicular communication network. In this paper, clustering schemes and robust power control schemes are utilized to achieve the improved spectral and energy efficiency. Clustering schemes are established to form stable clusters and pricing-based algorithms are used for achieving robust power control. The two robust power control algorithms the fixed price algorithm and optimized price algorithm are analyzed. And to compromise the trade-off produced by these algorithms, a pricing-based algorithm with delayed channel state information feedback for D2D (Device-to-Device) based vehicular communication network is developed in this paper. The results obtained shows that the proposed algorithm is effective.
