Abstract

Due to the high altitude advantage of unmanned aerial vehicles (UAVs), UAV crowdsensing has been extensively utilized in smart cities and harsh environments. However, UAVs have limited operational duration owing to energy constraints, dramatically diminishing their working efficiency. Moreover, their flight data is recorded and transmitted in unencrypted text, making it vulnerable to privacy breaches. We propose a privacy-preserving dual-model deep reinforcement learning approach (PD-DRL) to end it. It not only adaptively employs contextual knowledge to switch flight modes to enhance UAVs’ working efficiency but also safeguards the confidentiality of sensitive information during model training. PD-DRL consists of privacy-preserving deep reinforcement learning (P-DRL) and dual-model deep reinforcement learning (D-DRL). The former may integrate two distinct policies to switch between data collection and charging modes adaptively, hence optimizing the UAVs’ flight route. The latter can produce synthetic data to replace raw data during model training, thereby protecting the privacy of sensitive information. Ultimately, we conduct security discussions and comprehensive experiments to assess the effectiveness of PD-DRL. The discussion and experimental results demonstrate that PD-DRL surpasses other comparative algorithms, confirming its efficacy and safety.
PD-DRL:面向隐私保护和能源可持续的无人机众测
由于无人机的高空优势,无人机众测在智慧城市和恶劣环境中得到了广泛的应用。然而,由于能量限制,无人机的作战时间有限,极大地降低了其工作效率。此外,他们的飞行数据是以未加密的文本记录和传输的,这使得它很容易受到隐私侵犯。我们提出了一种保护隐私的双模型深度强化学习方法(PD-DRL)来结束它。它不仅能自适应地利用上下文知识切换飞行模式,提高无人机的工作效率,还能保障模型训练过程中敏感信息的保密性。PD-DRL包括保护隐私的深度强化学习(P-DRL)和双模型深度强化学习(D-DRL)。前者可以整合两种不同的策略,自适应地在数据采集和充电模式之间切换,从而优化无人机的飞行路线。后者可以在模型训练过程中生成合成数据来替代原始数据,从而保护敏感信息的隐私。最后,我们进行了安全性讨论和综合实验来评估PD-DRL的有效性。讨论和实验结果表明,PD-DRL优于其他比较算法,证实了其有效性和安全性。
