MADDPG-Based Energy Efficient Secure and Covert Transmission
Year: 2025
Type: conference-paper
Abstract: This paper presents a friendly-jammer-assisted framework for energy efficient secure and covert communication. We introduce a comprehensive metric termed average secrecy and covert energy efficiency (ASCEE) to characterize the trade-offs among energy efficiency (EE), physical layer security (PLS), and covert communication performance. An optimization problem is formulated to maximize the ASCEE metric. To address the challenges posed by cross-slot coupling constraints and the non-convex nature of the optimization problem, we propose a multi-agent Joint maximum ratio transmission (MA-MRT) algorithm. This approach deploys trained agents at both the source node and the jammer node, enabling adaptive control of transmit and interference power based on partially observed environmental state information. Simulation results demonstrate that the proposed algorithm achieves lower computational complexity compared to the greedy algorithm and exhibits superior performance in scenarios where the friendly jammer is positioned farther from the receiver node.
