Using Software Mitigation Schemes to improve the availability of IoT applications in harsh radiation environment

Abstract

The integration of IoT infrastructure in the context of particle accelerators promises numerous benefits (reduced costs and maintenance time, increased deployment). However, the use of microcontroller units (MCUs), typical of IoT systems, can potentially compromise future accelerator availability performances. This paper presents Software Mitigation Schemes (SMS) designed to improve the availability performance of MCU-based systems under radiation. Their effectiveness is demonstrated through a radiation test on a CERN Wireless IoT Radiation Monitoring system, also called BatMon. The results underline the IoT devices' feasibility as a viable solution for high-distribution systems in the High-Luminosity Large Hadron Collider (HL-LHC) or Future Circular Collider (FCC).
