Study Notes
IoT System Architecture
- IoT ecosystems start with sensors that convert physical phenomena like movement and temperature into digital signals.
- The power of IoT is in collecting vast amounts of sensory data, which is then transmitted to the cloud.
- Building a complete IoT ecosystem needs experts from different fields.
- Physicists are needed for creating sensor tech and batteries.
- Embedded systems engineers manage sensors at the edge.
- Network engineers handle PAN, WAN, and software-defined networking.
- Data scientists analyze data and create machine learning algorithms.
- DevOps engineers deploy scalable cloud and fog solutions.
- IoT architecture needs careful design choices for cloud storage, security, networking, and data analytics.
- Choosing the wrong protocol, like PAN, can cause poor communication and signal quality.
- Decisions about Internet protocols such as MQTT, CoAP, AMQP, and fog computing are vital for managing latency and bandwidth.
- IoT systems have five main parts: sensing and power, data communication, Internet/routing protocols, cloud/fog computing, and security.
- Sensors are now smaller and cheaper.
- Powering billions of sensors needs a lot of energy.
- New energy solutions like energy harvesting allow sensors to work for many years.
- Transmitting data from sensors to cloud services like Google, Amazon, and Microsoft comes with communication challenges.
- Unique addressing is needed for billions of IoT devices.
- Low-power communication helps reduce energy use.
- Efficient routing protocols are needed with low memory needs.
- High-speed, reliable communication is a must.
- IoT devices should be mobile.
- Non-IP communication like Bluetooth, RFID, and NFC is used for short-range PANs.
- IP-based communication connects IoT devices to the Internet.
- Key communication technologies include IEEE 802.15.4, low-power Wi-Fi, 6LoWPAN, RFID, NFC, Sigfox, and LoRaWAN.
- Gateways and routers connect IoT data from sensors to the Internet, providing secure, efficient, and low-latency communication.
- Cloud architectures (SaaS, IaaS, PaaS) process IoT data.
- Edge and fog computing reduce the need to transfer all data to the cloud.
- Advanced analytics and rules engines turn sensor data into useful insights.
- An example of this is detecting anomalies or using machine learning for real-time analytics.
- Security is a big concern because IoT devices are often in public, remote, or mobile locations.
- Encryption methods like asymmetric encryption can help reduce threats.
