Development for IoT will
include multiple domains such as green
building, smart grid, industrial
monitoring, agriculture, smart cities, healthcare, connected homes,
telematics and supply chain, safety and security, forest and wild life,
automotive, natural disasters, etc.
Agile development for IoT (Internet of Things) or Internet
of Services (IoS) involve three distinct stages as below:
1. Sensors which collect data (including identification and addressing
the sensor/device)
2. Application to collect and analyze this data for further
consolidation and,
3. Transmission of data to the decision support system. Agile
Analytics may be used for the development of decision making process.
Model Driven Architecture (MDA) can help accomplish agile
development fulfilling the fundamental requirement of complex association
between data collection points, iteratory / evolutionary development, change
management, version control etc. which include modeling of standard interfaces
associated with sensors.
For example IoT development for smart cities will include below
list of entities
• Smart parking. •
Intelligent transport system. •
Tele-care. • Woman Safety • Smart grids.
• eHealthcare. • Smart urban lighting.
• Waste management. • Smart city
maintenance. • Digital-signage. • Water Management
The data collection point can be done using model for each aggregated
entity using the entity model and association between the entities can be
defined. Then using entity modeling tool the interface can be modelled using
standard message, exception / error messages, events and protocol. This
modeling will help to generate soap / REST specification using either XML /
JSON / Text format as per convenience.
The entire process can be developed considering future
requirement for change management, version control and other non-functional
requirement such as single sign-on, caching, HA, event polling or pushing and
other utility services which are applicable from case to case. The information
flow can be designed using common data model, which will help the application
to collect the data and process based on data structure, specific business policy
and practices.
Following SOA principles of parallel development of system architecture
and business process architecture will help achieve agile development of
complete end to end IoT solution.
Your comments and feedback on specific issues with
aggregated entity and association between entities and agile development management
are welcome.
