State diagram based IoT Ecosystem's IoT device conflict problem migration method

State diagram based IoT Ecosystem's IoT device Conflict problem migration method. IoT provided an environment for controlling the embedded system in the network environment. As the embedded system is connected to the network, adaptation to various environmental changes was required. Self-adaptive systems have been researched to adapt to environmental changes. Also, due to the expansion of the system, concepts for operating the multiple system have emerged. However, studies to verify self-adaptive systems are lacking. In this paper, to verify the self-adaptation of the multiple system, a heterogeneous IoT device constituting the IoT ecosystem is represented by a State Diagram-based System Model. We confirmed the conflict problem between heterogeneous IoT devices through System Model of IoT Device. The conflict problem was migrated through the prioritization of the identified problems according to the environment.
