Mixed-Criticality Scheduling with Multiple Radio Interfaces

چکیده
Abstract In this chapter, we introduce the nodes with multiple radio interfaces (MRI) into mixed-criticality industrial wireless networks. When an error occurs or transmission demand changes, MRI can switch their mode, changing to a high-criticality configuration meet system’s new demand. Hence, first propose heterogeneous system model. Based on model, Slot Analyzing Algorithm (SAA) that guarantees schedulability by reallocating slots for each node after replacing conflict nodes. By considering both and cost, SAA also reduces number of Then, Priority Inversion (PIA) improves adjusting slot allocations before reducing use nodes, PIA achieves better performance than when is in mode.

Extending Mixed Criticality Scheduling
The capability of hardware is constantly developing in capacity, speed and efficiency. This development has sparked industrial and academic interest in how best to utilise the increased capability. It is now possible to integrate many systems that in the past might have existed as different nodes, into the one consolidated architecture. This desire to centralise functionality leads to the poten...
متن کاملMixed-criticality scheduling with memory regulation
The state-of-the-art models and schedulability analysis for mixed-criticality multicore systems overlook lowlevelaspects of the system. To improve their credibility, we therefore incorprate, in this work, the effects of delays from memory contention on a shared bus. Specifically, to that end, we adopt the predictable memory reservation mechanism proposed by the Single Core Equivalence framework...
متن کاملSemi-partitioned Mixed-Criticality Scheduling
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. Semipartitioning (whereby only some tasks migrate, in a carefully managed manner), hitherto used in single criticality systems, offers good performance with low overheads. Deadline-scali...
متن کاملGlobal mixed-criticality scheduling on multiprocessors
The scheduling of mixed-criticality implicit-deadline sporadic task systems on identical multiprocessor platforms is considered, when inter-processor migration is permitted. A scheduling algorithm is derived and proved correct, and its properties investigated. Theoretical analysis (in the form of both a speedup factor and sufficient schedulability conditions) as well as extensive simulation exp...
متن کاملOn the Safety of Mixed-Criticality Scheduling
A common assumption for scheduling mixedcriticality systems is the degradation of less critical tasks when the system is in the emergency mode; which is entered when critical tasks overrun their expected WCET. In the meanwhile, common safety standards enforce strict safety requirements on all criticality levels. However, the impact of degrading less critical tasks on the overall system safety i...
