The IoT platform design methodologies involve a comprehensive, multi-step approach to
developing robust, interoperable, and scalable IoT systems, covering all major aspects from
requirements to application deployment..
Key Methodology Steps
Purpose Requirement Specification
The first step is defining the purpose and capturing requirements like data collection,
analysis, system management, security, and user interface..
Example: A home automation system needs requirements for remote control,
monitoring, local data analysis, secure authentication, and behavior modes
(auto/manual)..
Process Specification
Derive specific use cases and define the processes involved from the high-level
requirements..
Includes decisions, state transitions, and attributes relevant to operations in the IoT
ecosystem..
Domain Model Specification
Defines main concepts, entities, and objects—physical entities (real-world items),
virtual entities (digital representations), devices, resources (software components),
and services..
Clarifies relationships, attributes, and associations independently of underlying
technology or platforms..
Information Model Specification
Details the structure of all information managed in the IoT system: attributes,
relationships, and connections among virtual entities..
Defines but does not describe the data representation or storage mechanisms..
Service Specification
Maps process and information models into clear service specifications: service types,
inputs/outputs, endpoints, schedules, preconditions, and effects..
Each service closely reflects instances and interactions defined in the domain model..
IoT Level Specification
Specifies the IoT level for the system, determining the abstraction and scope (device-
level, network-level, cloud-level, etc.)..
This mapping helps optimize system architecture and deployment options..
Functional View Specification
Describes the functions grouped into functional groups, outlining specific
functionalities, interactions, and information provision.
Details communication, hosting, and storage options for optimal system deployment.
Operational View Specification
Focuses on deployment and operational choices: how services are hosted, where
storage resides, application hosting, and various device options.
Integrates these choices for practical, scalable system operations.
Device and Component Integration
Integrates devices and software components to complete the physical and digital
interconnections required for IoT platform operation..
Covers connectivity, communication protocols, and system-wide
configuration.Application Development
The final step involves application design and deployment, ensuring user interfaces,
local/remote accessibility, and integration with backend services..
Example: Developing dashboards, model serialization, and API endpoints—using
frameworks like Django for backend integration.
Advantages of Structured IoT Design
Decreases design, testing, and maintenance time
Improves interoperability among modules and vendors
Reduces overall complexity, especially when building large-scale, multi-domain IoT
systems
