用决策树分析RFID信号实现军用物资定位,提升仓储安全监控能力。

Machine Learning-Based Localization Accuracy of RFID Sensor Networks via RSSI Decision Trees and CAD Modeling for Defense Applications

  • 基于CAD建模与真实RSSI数据构建决策树模型进行区域定位
  • 整体准确率34.2%,多个区域F1值超0.40,但少数区域仍易误判
  • 适用于低信号区异常检测,适合防御物资仓储场景

射频识别(RFID)追踪可能是符合安全规范的军事资产存储方案。然而传感器特异性差(存在远距离探测、伪造和仿冒等漏洞)可能导致错误检测和安全事件。本文采用监督学习模拟,使用真实接收信号强度指示(RSSI)数据,在计算机辅助设计(CAD)建模的平面图中进行决策树分类,涵盖12个实验区域(LabZoneA-L)。原始数据约98万次读取,类别分布不均,通过计算类别权重缓解不平衡问题。模型在分层抽样的5,000个平衡样本上训练,整体准确率为34.2%,多个区域(如F、G、H)F1值高于0.40。但罕见类别(尤其是LabZoneC)仍常被误判。通过邻接感知混淆矩阵提升物理相邻区域的解释性。结果表明,基于RSSI的决策树可在真实仿真中实现区域级异常检测或错位监控,用于军事物资物流管理。低覆盖率和弱信号区域的可靠分类可通过优化天线布局或融合其他传感器模态改善。

原文摘要 · Abstract (English)

Radio Frequency Identification (RFID) tracking may be a viable solution for defense assets that must be stored in accordance with security guidelines. However, poor sensor specificity (vulnerabilities include long range detection, spoofing, and counterfeiting) can lead to erroneous detection and operational security events. We present a supervised learning simulation with realistic Received Signal Strength Indicator (RSSI) data and Decision Tree classification in a Computer Assisted Design (CAD)-modeled floor plan that encapsulates some of the challenges encountered in defense storage. In this work, we focused on classifying 12 lab zones (LabZoneA-L) to perform location inference. The raw dataset had approximately 980,000 reads. Class frequencies were imbalanced, and class weights were calculated to account for class imbalance in this multi-class setting. The model, trained on stratified subsamples to 5,000 balanced observations, yielded an overall accuracy of 34.2% and F1-scores greater than 0.40 for multiple zones (Zones F, G, H, etc.). However, rare classes (most notably LabZoneC) were often misclassified, even with the use of class weights. An adjacency-aware confusion matrix was calculated to allow better interpretation of physically adjacent zones. These results suggest that RSSI-based decision trees can be applied in realistic simulations to enable zone-level anomaly detection or misplacement monitoring for defense supply logistics. Reliable classification performance in low-coverage and low-signal zones could be improved with better antenna placement or additional sensors and sensor fusion with other modalities.
