The Impacts of Write-Through Procedures and Checkpointing on Real-Time Concurrency Control

T.-W. Kuo
2003 Computer journal

Eva Kuhn, Richard Mordinyi, Mario Lang, Adnan Selimovic
2009 2009 IEEE/WIC/ACM International Joint Conference on Web Intelligence and Intelligent Agent Technology  
Multi-agent systems (MAS) is an accepted paradigm in safety-critical systems, like the production automation.  ...  Nevertheless, as any other distributed system MAS are prone to failures as well, and consequently an agent may crash.  ...  In case of coordinated checkpoints [12] , a consistent set of checkpoints forms a recovery line so that all agents can roll back to a consistent global state.  ...
