The Relationship

In this paper, we propose a novel resource allocation criterion based on physical layer security, which means choosing the proper subcarrier to ensure the device to device (D2D) security capacity maximum based on guaranteeing the cellular users basic capacity. We analyze the relationship between D2D security capacity and D2D power. We also prove that the strategies based on the D2D secrecy rate maximum and cellular sum rate maximum are the same when the transmit SNR of BS is high enough. Through the numerical calculation and simulation analysis, we show that the resource allocation criterion proposed in this paper is valid and rational.
