Study Notes

Non-IP Networking (NIN)

NIN is a communications technology that is designed to be more efficient and responsive than traditional IP-based networking.
Uses a virtual circuit approach where packets are classified into "flows" via a Software Defined Networking (SDN) model.

ZigBee

A wireless communication protocol designed for smart home devices.
Enables devices to form a mesh network, where each device can relay messages to others without relying on a central hub.
Low-power, low-cost, and low-data rate, making it ideal for long battery life and secure networking.
Examples of ZigBee devices: smart lights, plugs, locks, thermostats, sensors, and remotes.

Bluetooth

A wireless technology standard enabling devices to communicate over short distances without cables.
Commonly used to connect peripherals (headsets, speakers, game controllers, mice, keyboards) to other gadgets.
Can be used for file transfers between devices in the same room.

Modbus

A client/server data communications protocol in the OSI model's application layer.
Originally published by Modicon (now Schneider Electric) in 1979 for PLCs.
De facto standard communication protocol for communication between industrial electronic devices across buses and networks.
Popular in industrial environments due to being openly published and royalty-free.
Uses serial communication lines, Ethernet, or internet protocol suite as a transport layer.
Supports communication to and from multiple devices connected to the same cable or Ethernet network.

M-Bus

A European standard for the remote reading of water, gas, or electricity meters.
Can also be used for consumption meters in heating systems or water meters.
Interface designed for two-wire communication, making it cost-effective.
Uses serial communication lines as a transport layer.
Widely used in building control systems for measuring consumption data.

Wireless M-Bus (wM-Bus)

Open standard developed for power-efficient smart metering and Advanced Metering Infrastructure (AMI) applications.
Based on the M-Bus protocol.
Used for wireless communication between devices in Automatic Meter Reading (AMR) systems.
Quickly spreading in Europe for electricity, gas, water, and heat metering.
Network uses a star topology with master and slave devices as defined in EN 13757.
Operates in the 868 MHz frequency band and uses a maximum of 25 milliwatts of power.

Power Line Communication (PLC)

Communication technology that uses existing power lines to transmit data, voice, and video signals.
Also known as Power Line Telecommunications (PLT).
Used for a wide range of applications, including home automation and broadband internet access (broadband over power lines - BPL).
Different types of PLC technologies are needed for different applications, ranging from home automation to internet access.
Most PLC technologies are limited to one type of wire (premises wiring within a building), but some can cross between two levels (distribution network and premises wiring).
Transformers typically prevent signal propagation, requiring multiple technologies to form large networks.

IEEE 802.15.4

A technical standard defining the operation of a low-rate wireless personal area network (LR-WPAN).
Specifies the physical layer and media access control for LR-WPANs.
Designed for low-power, low-data-rate applications in Personal Area Networks (PANs) for IoT, embedded systems, and wireless sensor networks.
Known for low power consumption, extended battery life, mesh networking capabilities, and cost-effectiveness.

M2M Gateway

Used to enable communication between remote M2M area networks.
Required because non-IP based protocols are used within these networks, preventing direct communication with external networks.

Difference Between IoT and M2M

Communication Protocols: M2M systems use specialized protocols for machine-to-machine communication, while IoT systems typically utilize standard internet protocols.
Connectivity options: M2M often uses dedicated networks like 2G, 3G, or 4G, while IoT devices can connect to a broader range of networks.
Scale and heterogeneity: IoT systems typically involve larger scales and a wider variety of devices compared to M2M.
Data management and analysis: IoT systems often emphasize data management and analysis, while M2M focuses on real-time data transmission and control.

Hardware vs Software Emphasis

M2M emphasizes hardware with embedded modules, while IoT focuses more on software.
Data Collection and Analysis: M2M data is collected in point solutions and stored on-premises, while IoT data is collected in the cloud.
Applications: M2M data is accessed by on-premises applications, while IoT data is accessed by cloud applications.

SDN (Software-Defined Networking)

Separates the control plane from the data plane, centralizing the network controller.
Software-based SDN controllers maintain a unified view of the network, simplifying configuration, management, and provisioning.
Underlying infrastructure uses simple packet forwarding hardware instead of specialized hardware.

Key elements of SDN

Centralized Network Controller: Enables rapid network configuration.
Programmable Open APIs: Support programmable open APIs for interface between application and control layers.
Standard Communication Interface: Uses a standard communication interface between the control and infrastructure layers, with OpenFlow being a broadly accepted protocol.

NFV (Network Function Virtualization)

Leverages virtualization to consolidate network devices onto standard servers, switches, and storage.
Complementary to SDN as it provides the infrastructure on which SDN can run.

NFV

Aims to virtualize and abstract network functions from dedicated hardware into software-based instances.
