Behaviour-aware Hybrid Architecture for Trust-driven Transmissions

Researchers Dhrumil Bhatt and Anakha Kurup have introduced a behaviour-aware hybrid architecture for trust-driven transmissions, detailed in a new arXiv paper. The framework leverages Software-Defined Networking (SDN) to ensure secure, low-latency failover between heterogeneous communication channels in mission-critical aerospace and defence operations. It pairs a high-bandwidth primary link (e.g., satellite or tactical LTE) with a low-power fallback channel (e.g., RF or mesh), all governed by a zero-trust routing policy enforced by an SDN controller. A real-time Intrusion Detection System (IDS) continuously updates node trust scores; when trust or link reliability degrades, the controller autonomously switches traffic to the secondary channel, maintaining uninterrupted connectivity.

Simulation results in a Mininet-based test environment demonstrate sub-5 ms failover latency, efficient flow installation, and a significant reduction in packet loss compared to conventional single-channel or static routing systems. This scalable, resilient backbone is designed for autonomous platforms like UAVs, satellites, and ground control systems operating in contested or dynamic environments. By integrating cyber defence and autonomous coordination, the framework enhances mission reliability and network resilience against jamming, interference, and cyberattacks. The paper is available on arXiv under reference 2604.25201.
