TL;DR

A lightweight FL-based IDS tailored for drone swarm networks using deep neural networks (DNN) enhanced with knowledge distillation (KD) to reduce model complexity and communication costs without sacrificing detection performance.

Abstract

Drone swarms are increasingly deployed in critical applications such as surveillance, disaster response, and infrastructure monitoring. However, their reliance on open communication channels and their limited computational resources make them vulnerable to a wide range of cyber-threats. There is a growing interest in intrusion detection systems (IDS) specifically designed for drone environments and operations. However, the conventional solutions including Machine Learning (ML)-based approaches require collecting all data from heterogeneous drones in the swarm and processing on a central server may not be always feasible. Federated Learning (FL) has emerged as a promising distributed solution with an additional privacy-preserving feature. Even though potential studies exist, conventional FL-based IDS frameworks still face communication and computational overhead challenges, while achieving a balance between efficiency and effective detection under practical resource constraints remains a challenge. Therefore, we propose a lightweight FL-based IDS tailored for drone swarm networks using deep neural networks (DNN) enhanced with knowledge distillation (KD) to reduce model complexity and communication costs without sacrificing detection performance. We evaluate our framework using Raspberry Pi 4 devices and a real-world drone network dataset. Our approach demonstrates a detection accuracy of approximately 98.6% while reducing overall communication cost by around 70% and computational overhead by 29%. These results show that FL combined with KD is a practical and suitable solution for secure and efficient deployment in resource-constrained drone networks.

5G Network Intrusion Detection Method Based on Robust Federated Optimization

High-speed, low-latency and massive connectivity have emerged as a result of the rapid development of 5G networks, but so have security threats. Current intrusion detection tools are poorly adapted to the distributed, heterogeneous, and dynamic 5G environment where a flood of real-time information is generated over a spectrum of devices at the edges and network layers. Federated learning has been suggested in response to these threats as a new paradigm to aid in the training of intrusion detection systems without having to aggregate the information. This review provides a detailed study of intrusion detection systems in 5G networks that are federated learning-based, and how the federated learning-based intrusion detection systems can address the challenges mentioned above. The paper will also entail the discussion of the basic ideas and principles of federated learning, the importance of robust federated optimization techniques to enhance the robustness of models, and architectural design of distributed intrusion detection systems. Moreover, accuracy, efficiency, and resilience to adversarial attacks are also used as indicators of performance, which emphasizes the potential and strength of federated learning when used in complex network conditions. The key challenges and the difficulties, including the heterogeneity, communication, and security, are also discussed and analyzed. Lastly, the new trends and possible directions of research, such as the combination of AI explanations, adaptive learning, and federated learning with other emerging technologies, such as edge computing and blockchain, are also presented. In general, the paper provides a detailed and extensive perspective on the design and development of scalable and privacy-conserving and smart intrusion detection mechanisms on next-generation 5G networks.
