Computing utilization rate of Rate Monotonic scheduling mechanism in Controller Area Network
Utilization rate of hard real-time scheduling mechanism has an important effect on the schedulibility of real-time system like Controller Area Network. In this paper, based on the technique named bit-stuff and the maximum transmission time of frame we prove that if the priority of messages flow is allotted by Rate Monotonic (RM) policy and if requested capacity of CAN is not above 30% then time deadlines of all messages flow are met.
