AI中文摘要:
自主移动机器人的运行完整性依赖于无线控制回路的持续可用性,这使其成为对抗性故意电磁干扰的高度吸引目标。本文提出了一种弹性的跨层框架,将物理层频谱感知与网络层路由优化相结合,以在故意电磁干扰期间保护中间件(如ROS2)的稳定性。利用软件定义无线电前端,系统提取动态频谱描述符,包括频谱熵和信道占用率,以通知随机森林分类器建立自适应环境基线。为确保数据流不中断,该架构在热备用配置中维护双预认证物理接口,通过自动网络路由表更新实现瞬时故障切换。在物理ROS2移动机器人测试平台上的实证验证表明,这种自适应硬件辅助架构将通信恢复平均优化至141毫秒。这种亚秒级恢复直接转化为与软件重新关联相比,池化均方根路径跟踪误差减少78.9%,成功保障了系统级任务完整性。
英文摘要:
The operational integrity of autonomous mobile robots relies on the continuous availability of wireless control loops, making them highly attractive targets for adversarial intentional electromagnetic interference. This paper introduces a resilient, cross-layer framework that combines physical-layer spectral perception with network-layer routing optimization to protect middleware stability, such as ROS2, during intentional electromagnetic interference. Utilizing a software-defined radio front-end, the system extracts dynamic spectral descriptors, including spectral entropy and channel occupancy, to inform a Random Forest classifier that establishes adaptive environmental baselines. To ensure uninterrupted data flow, the architecture maintains dual pre-authenticated physical interfaces in a hot-standby configuration, enabling instantaneous failover through automated network routing table updates. Empirical validation on a physical ROS2 mobile robot testbed demonstrates that this adaptive hardware-assisted architecture optimizes communication recovery to an average of 141ms. This sub-second restoration translates directly into a 78.9% reduction in pooled root-mean-square path tracking error compared to software re-association, successfully securing system-level mission integrity.
