Mixed Criticality Scheduling for Industrial Wireless Sensor Networks [PDF]
Sensors, 2016 Wireless sensor networks (WSNs) have been widely used in industrial systems. Their real-time performance and reliability are fundamental to industrial production. Many works have studied the two aspects, but only focus on single criticality WSNs.

Flexible and Dynamic Scheduling of Mixed-Criticality Systems [PDF]
Sensors, 2022 A mixed-criticality system refers to an integrated embedded system in which tasks with different criticality levels run on a shared computing platform. In the design and development of mixed-criticality systems, how to schedule tasks to ensure that high ...

Task Migration and Scheduler for Mixed-Criticality Systems [PDF]
Sensors, 2022 The interference between software components is increasing in safety-critical domains, such as autonomous driving. Low-criticality (LC) tasks, such as vehicle communication, may control high-criticality (HC) tasks, such as acceleration.

Compensating Adaptive Mixed Criticality Scheduling
Proceedings of the 30th International Conference on Real-Time Networks and Systems, 2022 The majority of prior academic research into mixed criticality systems assumes that if high-criticality tasks continue to execute beyond the execution time limits at which they would normally finish, then further workload due to low-criticality tasks may

Multi-Core Time-Triggered OCBP-Based Scheduling for Mixed Criticality Periodic Task Systems [PDF]
Sensors, 2023 Mixed criticality systems are one of the relatively new directions of development for the classical real-time systems. As the real-time embedded systems become more and more complex, incorporating different tasks with different criticality levels, the ...

Semi-Clairvoyance in Mixed-Criticality Scheduling [PDF]
2019 IEEE Real-Time Systems Symposium (RTSS), 2019 In the Vestal model of mixed-criticality systems, jobs are characterized by multiple different estimates of their actual, but unknown, worst-case execution time (WCET) parameters.

Allocation algorithms for multicore partitioned mixed-criticality real-time systems [PDF]
PeerJ Computer ScienceMulticore systems introduced a performance increase over previous monocore systems. As these systems are increasingly finding application in critical domains, it arises a necessity to develop novel methodologies for their efficient resource allocation ...

Semi-partitioned Mixed-Criticality Scheduling [PDF]
ARCS, 2017 Scheduling isolation in mixed-criticality systems is challenging without sacrificing performance. In response, we propose a scheduling approach that combines server-based semi-partitioning and deadline-scaling. Semi-partitioning (whereby only some tasks migrate, in a carefully managed manner), hitherto used in single criticality systems, offers good ...

Mixed-Criticality Scheduling with I/O [PDF]
2016 28th Euromicro Conference on Real-Time Systems (ECRTS), 2015 This paper addresses the problem of scheduling tasks with differentcriticality levels in the presence of I/O requests. In mixed-criticalityscheduling, higher criticality tasks are given precedence over those of lowercriticality when it is impossible to ...

Expressing survivability considerations in mixed-criticality scheduling theory
Journal of Systems Architecture, 2020 Mixed-criticality scheduling theory (MCSh) was developed to allow for more resource-efficient implementation of systems comprising different components that need to have their correctness validated at different levels of assurance.
