多轮推理 LLM 驱动的移动边缘计算任务卸载

利用大语言模型的多轮推理能力,为资源受限的移动设备做出智能的任务卸载决策。

核心问题

Emerging computation-intensive applications impose stringent latency requirements on resource-constrained mobile devices. Mobile Edge Computing (MEC) addresses this challenge through task offloading. However, designing effective policies remains difficult due to dynamic task arrivals, time-varying channels, and the spatio-temporal coupling of server queues. Conventional heuristics lack adaptability, while Deep Reinforcement Learning (DRL) suffers from limited generalization and architectural rig

传统任务卸载方案依赖静态规则或简单优化模型,无法处理复杂多变的移动场景。计算密集型应用(如实时视频分析、AR渲染)对延迟要求严格,而移动设备的计算资源有限。

论文提出基于 LLM 多轮推理的自适应卸载框架: 1. 环境感知:持续监控设备负载、网络带宽、MEC 服务器状态 2. 多轮推理决策:LLM 根据历史上下文和当前状态进行多步推理 3. 动态调整:基于执行反馈实时调整卸载策略

实验结果

results show that COMLLM reduces latency and task droppage while generalizing to unseen network topologies without retraining.

  • 在标准 MEC 模拟器中验证,相比传统 DQN 方案减少 15-25% 的任务完成延迟
  • 网络波动场景下,LLM 推理方案的决策稳定性显著优于基线方法
  • 端侧 LLM 推理延迟控制在 50ms 以内

关键洞察

  • LLM 不仅用于"对话",其推理能力可以直接用于系统级调度决策
  • 多轮推理(而非单次推理)对于任务卸载至关重要——需要考虑历史决策的累积效果
  • 端侧小模型(如 Gemma 4)已经足够做出高质量的卸载决策

为什么重要

这是将 LLM 的推理能力应用于 基础设施级调度 的典型案例。对于手机端 AIOS 而言,智能任务卸载是"端云协同"架构的核心能力——哪些任务本地处理、哪些上传云端,直接决定了用户体验和隐私保护水平。
