Aerospace, automotive and aeronautical control systems demand high performance, precision, accuracy, modularity, integration, dependability and other attributes. Currently, to supply these requirements, engineers are using Networked Control Systems (NCSs) with Time Division Multiple Access (TDMA) databuses. They are part of Distributed Time Based Architectures (DTBAs) that provide the infrastructure for the design and implementation of safety critical distributed systems. These architectures provide a common time basis among the nodes of a system. However, the benefits of this approach face the challenge of establishing a common time basis among the nodes of a distributed system since startup until shutdown. For this, clock synchronization algorithms are used to achieve a common time basis within some precision and/or accuracy among the nodes of a system. So, clock synchronization algorithms become a critical part of designing distributed systems.
