Mechanism for Minimizing Stuffing-bit in CAN Messages

Abstract

In spite of wide acceptance of Controller Area Network (CAN) in industrial factory automation, limited bandwidth and nondeterministic response time have restricted the wider use of CAN in safety-critical real time systems. In this paper, a mechanism for minimizing stuffing-bit is proposed to reduce the length of CAN messages for the purpose of mitigating the affects of these problems. With this mechanism, it is observed that the message length is considerably reduced and the average bandwidth utilization is increased at the same time.
