Securing Large-Scale D2D Networks Using Covert Communication and Friendly Jamming [PDF]
IEEE Transactions on Wireless Communications, 2022 We exploit both covert communication and friendly jamming to propose a friendly jamming-assisted covert communication and use it to doubly secure a large-scale device-to-device (D2D) network against eavesdroppers (i.e., wardens).

Connectivity Times for Mobile D2D Networks [PDF]
2018 IEEE International Conference on Communications (ICC), 2018 Connectivity questions for mobile D2D networks are often approached by considering steady state performance metrics. This is due to the difficulty in handling a finite time horizon with random mobility. Hence, in this paper we create a framework to evaluate connectivity time in closed form over a finite time horizon for mobile devices. The basic metric
