Study Notes
Industry 4.0 and Industrial Internet of Things
- Energy-efficient network control protocol IEEE 1888 defines a generalized data exchange protocol between network components over IPv4/v6-based networks, using Universal Resource Identifiers (URIs) for data identification, with applications in environmental monitoring, energy saving, and central management systems.
Distributed Data Service Real Time Publish and Subscribe (DDS RTPS)
- Supports Publish/Subscribe framework on top of UDP transport layer protocol
- Data-centric and binary protocol, with data termed as “topics”
- Users/listeners can subscribe to topics of interest
- Supports enlisted QoS for data distribution, with applications in military, industrial, and healthcare monitoring
Quality of Service (QoS) Policies
- Reliability policy measures successful reception of reliable data from sender to receiver
- QoS policies for data delivery include transport priority, controlling the reliability level associated with data distribution
- Allows transmission of data according to its priority level
IoT Networking
- Requirements of IoT Network: high throughput, low latency, ultra-reliability, and high power efficiency
MQTT (Message Queue Telemetry Transport)
- Introduced by IBM and standardized by OASIS in 2013
- Works on Publish/Subscribe framework on top of TCP/IP architecture
- Advantages: reliable, lightweight, and cost-effective protocol
Enabling Classical Internet for IoT Devices
- Vendor specific gateways and APIs are proprietary non-IP based solutions with limitations in flexibility, interoperability, and last-mile connectivity
- IETF IP based solution includes IPv6 over Low power Wireless Personal Area Networks (6LoWPAN), Routing Over Low power and Lossy networks (ROLL), and Constrained RESTful Environments (CoRE)
IETF IP based solution
- IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) allows IPv6 packets to transmit and receive over IEEE 802.15.4 based networks through header compression and encapsulation
