CG-D2D: Cooperative Game Theory based Resource optimization for D2D Communication in 5G Wireless Network

Device-to-Device (D2D) communication have paved the way for resource allocation among a large number of wireless devices. A cooperative game theory based resource allocation in D2D communication for 5G wireless network is discussed in this article. Nearby devices combine to form a cluster and exchange data between themselves. Due to the short distance between the devices into the cluster, the amount of data loss between them is much less. In CG-D2D, a utility function and two algorithms are proposed through which spectrum manager allocate the resources between devices in the cluster and allocate the resources among the clusters. In this article, the power consumption, Signal to Interference plus Noise Ratio (SINR) and spectral efficiency (SE) of proposed CG-D2D are calculated and compared it with the existing networks. The proposed CG-D2D reduces the power consumption by approximately 10% – 30% and enhances the SINR and spectral efficiency (SE) by approximately 2% – 8% and 2% – 4% respectively than the existing approaches.
