Life-cycle management of IoT and IIoT with Device used in IoT and IIoT

Internet of Things (IoT) systems and the corresponding network architectures are complex due to distributed services on many IoT internet of Things (IoT) systems and the corresponding network architectures are complex due to distributed services on many IoT devices collaboratively fulfilling common goals of IoT applications. System requirements for different types of IoT application domains are still not well-established. The life cycle view is one of the views used for system architecting, showing different stake holders’ concerns at every stage of the life cycle to derive system requirements. We employ the life cycle view to under-stand IoT systems in different IoT application domains. Our contribution is the definition of a generic life cycle model for IoT, which is specified by observations
