Identifying Partial Subroutines for Instrument Control Based on Regular Expressions

With increasing reliance on smart devices to communicate with each other to deliver critical services, it is important that the devices become intelligent and reliable. Such devices are widely used in Internet of Things applications that operate on the Internet. These devices often communicate with new nodes and face new situations while interacting with them. This paper focuses on providing a generalized description of the communication between a particular pair of devices. This description is based on regular expressions from automata theory. The regular expressions enable the devices to determine the properties of future interactions with other similar devices. This can help the nodes to validate incoming commands, evaluate the interactions and maintain a reasonable quality of service. A particular IoT application - a Remote Access Laboratory system, is shown as an example where the regular expressions can be used. This application aims to use the regular expressions based generalized descriptions to identify potential subroutines from previously stored interaction data.
