D2D Resource Allocation and Power Control Algorithms Based on Graph Coloring in 5G IoT

Abstract

Device-to-Device (D2D) is a promising 5g Internet of Things communication scheme. Green Internet of Things (IOT) with low energy consumption is an important research topic at present. The most important problem is how to allocate resources and control power. Based on the traditional algorithm based on graph theory coloring principle, this paper proposes a resource allocation algorithm which combines power control and node priority calculation, and optimizes the communication index as a whole. The simulation results show that the proposed algorithm can improve the performance of delay, fairness and throughput while maintaining low power consumption.
