Global: Study Explores Antifragility of RIS-Assisted Links Against Jamming Attacks

Researchers Mounir Bensalem, Thomas Röthig, and Admela Jukan released a preprint on arXiv that investigates how reconfigurable intelligent surface (RIS)‑enabled communication links can exhibit antifragile behavior when subjected to jamming attacks. The work was first submitted on 5 May 2025 and revised on 13 Jan 2026, offering a cross‑layer analysis that bridges link‑level performance with multi‑hop network dynamics.

Background on Antifragility and RIS Technology

Antifragility, originally an economic concept describing systems that benefit from volatility, is applied here to wireless networks. RIS technology allows programmable manipulation of electromagnetic waves, creating adaptive propagation environments that can potentially turn adverse conditions into performance gains.

Methodological Framework

The authors model several jamming scenarios—including constant, intermittent, and smart adaptive jammers—and assess RIS‑assisted links across physical, MAC, and network layers. Simulations compare baseline non‑RIS links with RIS‑enhanced counterparts, measuring metrics such as signal‑to‑interference‑plus‑noise ratio, packet delivery ratio, and end‑to‑end throughput.

Key Findings at the Link Level

Results indicate that, under certain jamming models, RIS‑assisted links achieve higher signal quality and can recover throughput losses that would otherwise degrade the network. The analysis demonstrates measurable antifragile gains, meaning the links not only withstand interference but also improve relative to a non‑jamming baseline.

Network‑Level Implications

Extending the link‑level benefits to multi‑hop topologies, the study shows enhanced end‑to‑end resilience, increased connectivity probability, and sustained throughput across the network. These improvements suggest that integrating RIS‑enabled nodes could be a viable strategy for designing robust communication infrastructures in contested environments.

Potential Applications and Limitations

The findings have relevance for military, emergency response, and industrial IoT deployments where adversarial interference is a concern. However, the authors note that practical implementation would require precise channel state information and real‑time RIS configuration, challenges that merit further investigation.

Future Research Directions

Future work is proposed to explore hardware prototypes, adaptive control algorithms, and the interplay between RIS‑based antifragility and higher‑layer security protocols. Such studies could clarify the trade‑offs between system complexity and the observed resilience benefits.
