Local Model Checking on an IoT Based System: Use Case of Cellular M2M in Agriculture
Résumé
Our method of limiting the verification of a linear temporal logic (LTL) property of a modular system to the pertinent modules is improved in this study. Given a modular Petri net and a property pertaining to a single module, the model verification is performed by looking simply at an abstract graph, known as the meta-graph, which is supplemented with some global information and describes the behaviors of the module. Reduced Distributed State Space (RDSS), a distributed state space version of the studied modular system, eliminates the need to examine graphs of unrelated modules for the property. In this work, the state space is built only once. The response time for local model verification is greatly reduced as we can now examine a set of properties for every module in a single request. Following that, we examine whether our methodology may be applied in the quickly growing field of "machine-to-machine (M2M) technology." We specifically look at a use case in agriculture that involves cellular M2M. The modular design of this system makes it possible to construct its RDSS and then apply local model checking to verify the properties of each module.
