There exists an virtually bewildering choice of connectivity choices for electronics engineers and application developers engaged on products and programs for the Internet of Things (IoT). Layering is a design principle which divides the protocol design activity into smaller steps, every of which accomplishes a particular part, interacting with the opposite elements of the protocol solely in a small variety of properly-defined methods. SAE J1939 is a high degree communications protocol, which operates on a Controller Space Network (CAN) bus.

At this level, the master module may initiate the present design communications protocol by sending an express request message to start out communications. Excessive communications protocol overhead, or poor protocol effectivity, can require additional transmission media (i.e. fixed wire or cable) bandwidth to appreciate change of management and status data between modules.

Which abstracts the details of the protocol and allows a simple description of the service offered by the …
