Overview
IoT networking faces unique challenges: devices are often battery-powered, have limited processing power, and may be located in remote or harsh environments. Traditional protocols like TCP/IP are often too 'heavy' for these devices.
Key Technologies
- Low-Power Wide-Area Networks (LPWAN): LoRaWAN, Sigfox, NB-IoT.
- Short-Range Wireless: Zigbee, Z-Wave, Bluetooth LE.
- Lightweight Protocols: MQTT, CoAP.
- IPv6 Adaptation: 6LoWPAN allows IPv6 to run over low-power wireless links.
Challenges
- Security: Many IoT devices have weak security and are difficult to patch.
- Scalability: Managing and monitoring millions of connected devices.
- Interoperability: Ensuring devices from different manufacturers can communicate.
