Study Notes
Messaging Protocols
- MQTT (Message Queue Telemetry Transport) is based on the publish-subscribe model, making it suitable for IoT devices.
- MQTT is well suited for IoT devices with limited processing and memory resources and low network bandwidth.
Data-Centric Middleware
- DDS (Data Distribution Service) is a data-centric middleware standard for machine-to-machine communication.
Request-Response Model
- CoAP (Constrained Application Protocol) uses a request-response model like HTTP but runs on top of UDP instead of TCP.
Full-Duplex Communication
- WebSocket allows full-duplex communication over a single socket connection for sending messages between client and server.
M2M Communication
- CoAP is specifically designed for machine-to-machine (M2M) applications in constrained environments.
Internet Protocol
- IPv6 is the newest and successor to IPv4.
IPv6 Address Scheme
- The 128-bit address scheme used in IPv6 allows a total number of 2^128 addresses.
6LOWPAN
- 6LOWPAN operates in the 2.4 GHz frequency range for data transfer.
Transport Layer Protocol
- TCP (Transmission Control Protocol) is a connection-oriented and stateful transport layer protocol.
