In this paper, the security in a device-to-device (D2D) spectrum sharing network is investigated. The cellular users and eavesdroppers are distributed according to two independent Poisson Point Processes (PPPs), and the positions of the D2D transmitters follow a hard-core point process. Based on the stochastic geometry, we first derive closed-form expressions of the connection and secrecy outage probabilities...
Millimeter wave (mmWave) communication has been a promising technology of future fifth generation (5G) cellular networks. Due to the tremendous propagation loss of mmWave communication, device-to-device (D2D) communications are widely used over directional mmWave networks to improve the network throughput. In this paper, a new time resource sharing scheme is proposed based on Stackelberg game for...
In this letter, the issue of security for device-to-device (D2D) underlaying cellular networks is considered. The cellular communication is overheard by randomly distributed eavesdroppers. By sharing the spectrum between D2D users and cellular users, the interference generated by D2D users is used as a source of jamming to confuse the eavesdroppers. We first derive the connection probability of the...
