Two novel shared-clock scheduling algorithms for use with ‘Controller Area Network’ and related protocols

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.
