In this paper, we investigate the optimization of the monitoring rate for a suspicious multicast communication network with a legitimate full-duplex (FD) monitor, where the FD monitor is proactive to jam suspicious receivers and eavesdrop from the suspicious transmitter simultaneously. To effectively monitor the suspicious communication over multicast networks, we maximize the monitoring rate under the outage probability constraint of the suspicious multicast communication network and the jamming power constraint at the FD monitor. The formulated optimization problem is nonconvex, and its global optimal solution is hard to obtain. Thus, we propose a constrained concave convex procedure- (CCCP-) based iterative algorithm, which is able to achieve a local optimal solution. Simulation results demonstrate that the proposed proactive eavesdropping scheme with optimal jamming power outperforms the conventional passive eavesdropping scheme.

具有全双工主动监视功能的可疑组播通信网络的速率最大化

在本文中，我们研究了使用合法全双工（FD）监视器的可疑多播通信网络的监视速率的优化，其中FD监视器会主动阻塞可疑接收器并同时从可疑发送器进行监听。为了有效地监视多播网络上的可疑​​通信，我们在可疑多播通信网络的中断概率约束和FD监视器的干扰功率约束下最大化了监视速率。所提出的优化问题是非凸的，并且难以获得其全局最优解。因此，我们提出了一种基于约束凹凸过程（CCCP）的迭代算法，该算法能够实现局部最优解。
