Power and Spectrum Efficient D2D Communication for 5G IoT Using Stackelberg Game Theory

Internet of Things (IoT) is a necessary element for creating a smart environment in 5G wireless communications. In this article, we proposed a power and spectrum efficient Device-to-Device (D2D) communication based IoT using Stackelberg game. IoT devices exchange the information's between them directly without accessing the base station, and when they need to send data to the other network, they transmit the data using a femtocell base station. In this article, we proposed a utility function for selecting the leader IoT device from each cluster based on the minimum distance between the IoT device and femtocell base station. We calculated the power consumption, Signal to Interference plus Noise Ratio (SINR) and spectral efficiency of the proposed network and compared with existing approaches. The power consumption of the proposed network reduces by approximately 35% and SINR and spectral efficiency increases by approximately 6% and approximately 4% respectively than the existing approaches.
