English abstract:
This paper analyzes and discusses the interface models of the three real-time smart transducer networks COSMIC, LIN, and TTP/A.
The COSMIC architecture follows a publish/subscribe model, where the producing smart devices broadcast their event data on the basis of a push paradigm. Subscribers receive data in form of a message-based interface.
LIN follows a strict pull principle where each message from a device node is requested by a respective message from a master. Applications have a message-based interface in order to receive and transmit data.
The nodes in a TTP/A network derive its sending instants from predefined instants in time. TTP/A maps communicated data into an Interface File System (IFS) that forms a distributed shared memory.
