Lecture 1-Part 2
- The IoT ecosystem is a connection of various kinds of devices that sense and analyze the data and communicates with each other over the networks.
- In the IoT ecosystem, the user uses smart devices such as Smartphone’s, tablet, sensors, etc. to send the command or request to devices for information over the networks.
The characteristics of iot devices
With regard to the IoT, anything can be interconnected with the global information and communication infrastructure.
Heterogeneity:They can interact with other devices or service platforms through different networks.
Dynamic changes:The state of devices change dynamically, e.g., sleeping and waking up, connected and/or disconnected as well as the context of devices including location and speed.
Safety:This includes the safety of our personal data and the safety of our physical well-being. Securing the endpoints.
Intelligence:The aspect of intelligence as in the sensing capabilities in IoT devices and the intelligence gathered from big data analytics (also artificial intelligence).
Various technologies making up IoT ecosystem
Sensing, Embedded processing, Connectivity:
Smart devices and environment, Cloud Computing:
Technology, Software, Application:
The IoT ecosystem uses any of different technologies, software and application to communicate and connect with smart devices and environment.
Users or groups of community
The product or services generated by the IoT ecosystem are consumed by the users or the group of communities to serve the smart life.
Examples & Applications
- Asset Tracking:Whether the assets are big or small, fixed or mobile, attaching sensors to them allows organizations to track real-time location, monitor performance, and optimize utilization.
Energy Efficiency:Sensors monitor things like lighting, temperature, energy usage, etc. and that data is processed by intelligent algorithms to micromanage activities in real-time.
For outdoor agriculture:Example could be sensing soil moisture and taking weather into account so that smart irrigation systems only water crops when needed, reducing the amount of water usage.
For indoor agriculture:IoT allows monitoring and management of microclimate conditions (humidity, temperature, light, etc.) to maximize production.
Disaster Warning: Sensors can collect critical information about the environment, allowing for early detection of environmental disasters like earthquakes, tsunamis, etc., thus saving lives.
The building blocks of IoT
- Things:The right hardware and peripherals. Directly or indirectly connects to the Internet. The Process the data captured by the sensors.
Local Services:The IoT system and give intelligence to the data before it’s transmitted. The Processors mostly work on a real-time basis and can be easily controlled by applications. The Processors also perform encryption and decryption maintain security of communication.
Gateways:With the help of gateways, machinery on a production line can relay information that alerts service technicians to impending maintenance problems.
Platform: The easily connects devices and sensors and enables connections between related information systems and operational assets.
Applications:The software element of the system
