D2D communication channel allocation and resource optimization in 5G network based on game theory

摘要

With the rapid development of intelligent hardware and the Internet of Things, the bandwidth and resource utilization efficiency of related networks need to be improved. At the same time, the corresponding communication spectrum is becoming more and more scarce. At present, cognitive D2D communication technology in 5G network can establish communication link directly through communication equipment, so that two established communication equipment can realize direct communication, so as to make full use of communication resources and finally meet the explosive growth of traffic demand. How to manage communication resources and select communication links is the main research direction of D2D communication technology in 5G technology. Based on the knowledge of game theory, this paper proposes a communication channel allocation scheme and resource optimization scheme based on spectrum clustering and non cooperative game to maximize the operation efficiency of D2D communication equipment. The actual efficiency can reach about 1.5 times of the original communication efficiency. Finally, the optimization method proposed in this paper is compared with the traditional communication method. The experimental results show that this method has higher advantages.
