摘要:

近年来,强化学习(RL)已被应用于无线通信网络中的抗对抗措施。然而,从对手的角度研究基于RL的方法很少受到关注。此外,在对抗或对抗范例中基于RL的方法主要考虑单信道通信(信道选择或单信道功率控制),而多信道通信在实践中更常见。在本文中,我们提出了一个多代理对手系统(MAAS)的建模和分析对手在无线通信场景下仔细设计的奖励功能,在现实的通信场景。特别是,通过将对手建模为学习代理,我们表明,所提出的MAAS能够成功地选择传输信道及其各自的分配功率,而无需任何发送方策略的先验知识。与单智能体对抗(SAA)相比,多智能体在相同的功率约束和部分可观测性条件下,可以显著降低系统的信噪比(SINR),同时提高系统的稳定性和学习效率。此外,通过实证研究,我们表明,在模拟的结果是接近的,在现实中的通信,一个结论是关键的有效性模拟评估代理的性能。

英文摘要:

Recently Reinforcement Learning (RL) has been applied as an anti-adversarial remedy in wireless communication networks. However, studying the RL-based approaches from the adversary's perspective has received little attention. Additionally, RL-based approaches in an anti-adversary or adversarial paradigm mostly consider single-channel communication (either channel selection or single channel power control), while multi-channel communication is more common in practice. In this paper, we propose a multi-agent adversary system (MAAS) for modeling and analyzing adversaries in a wireless communication scenario by careful design of the reward function under realistic communication scenarios. In particular, by modeling the adversaries as learning agents, we show that the proposed MAAS is able to successfully choose the transmitted channel(s) and their respective allocated power(s) without any prior knowledge of the sender strategy. Compared to the single-agent adversary (SAA), multi-agents in MAAS can achieve significant reduction in signal-to-noise ratio (SINR) under the same power constraints and partial observability, while providing improved stability and a more efficient learning process. Moreover, through empirical studies we show that the results in simulation are close to the ones in communication in reality, a conclusion that is pivotal to the validity of performance of agents evaluated in simulations.
