A new architecture (FlexCAN) and associated protocol (SafeCAN) is sumarized. The new architecture and constituent protocol are based on the CAN protocol and supports embedded safety-critical applications such as those in vehicles (trucks, cars, boats, snowmobiles, etc). The paper concentrates on the paradigms used by the architecture and the various(More)
This paper describes the design of a drive-by-wire system for a commercial lift truck using the FlexCAN communication architecture. FlexCAN is a recently developed architecture based on the CAN protocol to support deterministic and safety-critical applications. The main features of FlexCAN are its simplicity and ready implementation based on COTS CAN(More)
Most IoT architectures are either too complex and difficult to use or too simple and not generic enough. We propose an architecture that balances important architectural requirements suited for the IoT and particularly the Industrial Internet. The proposed architecture sheds new light into the complex nature of the IoT.
This paper is concerned with the issue of protecting CAN networks against the consequences of babbling-idiot faults such as unscheduled traffic generated by a faulty node that denies any other communication. A full solution of the problem would greatly enhance the dependability of the CAN networks, making them applicable to safety-critical systems. After(More)
A new fault management protocol that makes use of native fault tolerant features of TTP/C has been developed. It can tolerate multiple nodes failures no matter how close in time and in minimum time. The time it takes to detect a node failure and to reconfigure the system is minimum and it is fixed by the TTP/C protocol. The protocol tolerates that several(More)
