A Game Theory Scheme Combined with the Interference Region in Cellular D2D Heterogeneous Networks

The cellular D2D heterogeneous network takes advantage of proximity gain and hop gain of D2D communication, which can greatly improve the performance of the entire network. The actual network imposes an ultra-reliable and low-latency requirement for communications. Therefore, this paper proposes a set of joint power control and resource allocation distributed solutions. It consists of two parts. In order to guarantee the quality-of-service (QoS) of cellular primary users and scheduled D2D users, the pricing-based game scheme is used. In order to achieve the low-latency requirement, the link scheduling scheme based on the interference graph matrix within the D2D network is proposed. Simulations have shown that compared with the pure game theory scheme, this scheme can significantly reduce delay and thus achieve ultra-reliable and low-latency requirements.
