Engineering Opportunistic Digital Twins with Lingua Franca
Digital Twins (DTs) are evolving from passive digital shadows into intelligent and adaptive systems empowered by AI. This work focuses on Opportunistic Digital Twins (ODTs), a new class of DTs that dynamically exploit edge–cloud resources to enhance the representation and control of Cyber-Physical Systems (CPS). We introduce an engineering approach for building dependable ODTs using the deterministic concurrency and explicit timing semantics of Lingua Franca (LF). A Smart Traffic Management case study on Emergency Vehicle Preemption (EVP) demonstrates how ODTs can adapt model selection at runtime while preserving deterministic coordination across distributed nodes. Results show that LF-based ODTs improve reliability, adaptability, and scalability in intelligent CPS deployments.

Edge AI in the computing continuum: Consistency and Availability at Early Design Stages
This paper integrates Edge Intelligence (EI) with the coordination language Lingua Franca (LF), using the Consistency-Availability-Latency (CAL) theorem to optimize Cyber-Physical Systems (CPS). We demonstrate an Emergency Vehicle Detection (EVD) system that prioritizes emergency vehicles through multimodal detection and LF’s deterministic coordination. Two deployment scenarios are evaluated—cloud-assisted and fully edge-based—guided by CAL tradeoffs. Experiments show that the edge-based solution reduces inference-to-actuation latency by 2.8x and energy consumption by 10.26%, while eliminating cloud bandwidth overhead.
