Özet
Industrial Internet of Things applications increasingly rely on 6TiSCH networks to provide deterministic latency, high reliability, and energy-efficient communication. However, the integration of RPL routing exposes 6TiSCH networks to routing attacks, among which the blackhole attack represents a particularly severe threat. In such attacks, malicious nodes advertise falsified routing metrics to attract traffic and subsequently drop data packets while remaining protocol-compliant. The problem becomes more challenging in dynamic industrial environments, where node mobility, frequent parent switching, and TSCH resynchronization introduce packet losses that closely resemble malicious behavior. This paper proposes MobiTrust-6T, a trust-aware security framework designed to detect and mitigate mobile blackhole attacks in RPL-based 6TiSCH networks. It employs a telemetry-driven trust model that jointly evaluates packet forwarding behavior and topology stability, enabling the differentiation of malicious packet drops from mobility-induced disruptions. A hybrid mitigation strategy is adopted, combining centralized trust evaluation at the 6TiSCH root with localized topology recovery to rapidly isolate detected attackers without triggering costly global repairs. The effectiveness of MobiTrust-6T is evaluated through extensive simulations using Contiki-NG and the Cooja simulator under grid and random topologies with mobile attackers. Experimental results demonstrate that MobiTrust-6T significantly improves packet delivery ratio compared to attacked RPL while maintaining moderate control packet overhead.
