LLM-Enabled In-Context Learning for Data Collection Scheduling in UAV-assisted Sensor Networks

  • 通过大模型解析自然语言任务描述,动态生成采集调度方案。
  • 相比DQN和最大信道增益方法,累计丢包率显著降低。
  • 适合紧急救援等对响应速度要求高的无人机传感网络场景。

无人机在交通管制、快递配送和搜救任务等场景中应用日益广泛。现有基于深度强化学习的无人机辅助传感网络(UASNETs)面临模型训练复杂耗时、仿真与现实差距大、采样效率低等问题,难以满足紧急任务需求。本文提出一种基于上下文学习(ICL)的数据采集调度系统(ICLDC),替代传统DRL。无人机收集感知数据并传至大语言模型(LLM),LLM将任务转化为自然语言描述,据此生成需执行的数据采集计划;一个验证器根据预设规则评估并覆盖不安全调度。系统通过反馈持续迭代优化。实验测试了越狱攻击下的鲁棒性,揭示了LLM在任务描述被操纵时的脆弱性。ICLDC在减少累积丢包方面显著优于DQN与最大信道增益基线,展现出在UASNETs中智能调度与控制的潜力。

原文摘要 · Abstract (English)

Unmanned Aerial Vehicles (UAVs) are increasingly being utilized in various private and commercial applications, e.g., traffic control, parcel delivery, and Search and Rescue (SAR) missions. Machine Learning (ML) methods used in UAV-Assisted Sensor Networks (UASNETs) and, especially, in Deep Reinforcement Learning (DRL) face challenges such as complex and lengthy model training, gaps between simulation and reality, and low sampling efficiency, which conflict with the urgency of emergencies, such as SAR missions. In this paper, an In-Context Learning (ICL)-Data Collection Scheduling (ICLDC) system is proposed as an alternative to DRL in emergencies. The UAV collects sensory data and transmits it to a Large Language Model (LLM), which creates a task description in natural language. From this description, the UAV receives a data collection schedule that must be executed. A verifier ensures safe UAV operations by evaluating the schedules generated by the LLM and overriding unsafe schedules based on predefined rules. The system continuously adapts by incorporating feedback into the task descriptions and using this for future decisions. This method is tested against jailbreaking attacks, where the task description is manipulated to undermine network performance, highlighting the vulnerability of LLMs to such attacks. The proposed ICLDC significantly reduces cumulative packet loss compared to both the DQN and Maximum Channel Gain baselines. ICLDC presents a promising direction for intelligent scheduling and control in UASNETs.
