Abstract

Abstract The Controller Area Network (CAN) protocol is widely employed in the development of distributed embedded systems. Previous studies have illustrated how a “Shared-Clock” (S-C) algorithm can be used in conjunction with CAN-based microcontrollers to implement time-triggered network architectures. This study explores some limitations of the existing S-C algorithms (“TTC-SC1” and “TTC-SC2”), and introduces two new algorithms (“TTC-SC3” and “TTC-SC4”). The results presented in the paper suggest that TTC-SC3 and TTC-SC4 are useful additions to the range of shared-clock algorithms.
