A SAFE AND EFFICIENT PROTOCOL FOR OASIS-BASED DISTRIBUTED SAFETY-CRITICAL REAL-TIME SYSTEMS

In most key industries, distributed real-time systems have found widespread use in order to ensure safety-critical functions. Design of such systems still represents a challenge because of many problems arisen by the combination of real-time, distribution, performance and safety. Fault-tolerant real-time networks have been a major research subject for these last years. OASIS provides a time-triggered multitasking and communication approach for designing safety-critical real-time systems. In order to fulfil the industrial needs, an extension to distributed architectures has been carried out which includes a TDMA-based deterministic and real-time protocol and its optimized version, called A-TDMA, presented here.
