    Study Notes

    IoT Design Methodology Steps

    • Purpose & Requirements: Defines IoT system goals, user needs, business objectives, cost reduction, efficiency, user convenience. Considers budget, technical feasibility, and stakeholder needs. Deliverables include a problem statement, system goals, and requirements.
    • Process Model Specification: Defines use cases and system behavior, detailing user interactions, data collection, and workflows (data processing, actuation). Deliverables include use case diagrams and process workflows.
    • Domain Model Specification: Identifies physical entities (sensors), virtual entities (cloud services), resources/services, defines components, interfaces, and maps data sources. Deliverables include a domain model diagram.
    • Information Model Specification: Defines data structure, storage, processing. Outlines data types, attributes, data flows, addressing metadata and security policies. Deliverables include information models (e.g., ERDs).
    • Service Specifications: Defines system services (data collection, analysis, actuation). Ensures interoperability by outlining APIs and communication endpoints. Deliverables include service descriptions and API documentation.
    • IoT Level Specification: Determines IoT system architecture (cloud-centric, edge-centric, D2D, D2C, D2G). Defines communication hierarchy. Deliverables include an IoT architecture diagram.
    • Functional View Specification: Maps system into modules (sensing, data processing, storage). Assigns roles to each module and defines interactions. Deliverables include functional block diagrams.
    • Operational View Specification: Defines system protocols, data storage, hosting, and deployment strategies (Wi-Fi, Zigbee, LoRaWAN). Deliverables include operational design documents.
    • Device & Component Integration: Integrates hardware (sensors, actuators, communication modules). Tests system compatibility for smooth interfacing. Deliverables include an integrated prototype.
    • Application Development: Creates user interfaces (apps, dashboards, APIs). Ensures usability, scalability, and performance. Deliverables include fully developed applications ready for deployment.
