Dynamic Clustering Method for the Massive IoT System

Abstract

AbstractThis study suggests a dynamic clustering method that can regroup, change, add, or remove groups of specific IoT devices according to the user’s demands without reinstalling or reconfiguring the system in an environment where multiple IoT devices are collectively used. In the dynamic clustering method, IoT devices can be freely and logically connected to other cluster controllers, since IoT devices are connected to a cluster controller through a logical network. Since a cluster that performs a specific group control can be dynamically configured without changing a physical network connection, IoT devices included in the cluster can also be dynamically organized or logically relocated as needed. Through this dynamic clustering method, the user can change the control groups of IoT devices as necessary and perform group control. The dynamic clustering method requires a dynamic cluster controller that supports logical connections with IoT devices. The dynamic cluster controller physically connects several IoT devices. However, the actual function control is performed in a logically connected group unit through a PLM table shared by all cluster controllers. The PLM table is implemented so that the dynamic cluster controller can be composed of any logical group regardless of the physical connection. Through this method, the user can dynamically configure the logical segment suitable for the required situation. The dynamic clustering method proposed in this study can implement efficient and organic, dynamic group control as it can control the IoT devices of the cluster in logical group units. Thus, the method can be developed as a vital technology to be refined and utilized as an essential advanced technology to construct an IoT environment that adapts the rapidly changing modern IT environment in real time.KeywordsIoT deviceDynamic clusteringPLM tableLogical IoT clusterMassive control
