IoT Modeling and Verification: From the CaIT Calculus to UPPAAL

With the support of emerging technologies such as 5G, machine learning, edge computing and Industry 4.0, Internet Things (IoT) continues to evolve promote construction future networks. Existing work on IoT mainly focuses its practical applications, but there is little research modeling interactions among components in systems verifying correctness network deployment. Therefore, Calculus (CaIT) has previously been proposed formally model reason about systems. In this paper, CaIT calculus extended by introducing broadcast communications. For convenience, we provide explicit operations node mobility well between sensors (or actuators) with environment. To use UPPAAL verify temporal properties networks described calculus, establish a relationship timed automata calculus. Using UPPAAL, six simple “smart home” example, including Boiler On Manually, Off Automatically, Lights On, Mutually, Windows Simultaneously. The verification results show that can properly.
