Infrastructure Definitions

  • M

    MQTT (MQ Telemetry Transport)

    MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol that provides sensors and other resource-constrained network clients with a simple way to distribute telemetry information. The protocol, which employs a publish/subscribe communication pattern and is managed by OASIS, is used for machine-to-machine (M2M) communication in the Internet of Things (IoT).

  • P

    pervasive computing (ubiquitous computing)

    Pervasive computing (ubiquitous computing) is the growing trend of embedding computational capability into everyday objects to enable them to communicate and perform useful tasks.

  • R

    reference architecture

    A reference architecture is a document or set of documents to which a project manager or other interested party can refer to for best practices. By using a reference architecture, a project team can potentially save time and avoid mistakes by learning from past experiences.

  • remote sensing

    Remote sensing is the use of various technologies to make observations and measurements from a target that is usually at a distance or on a scale beyond those observable to the naked eye. Remote sensing technologies include: LiDAR, radar, infrared radiation (IR), thermal, seismic, sonar, electric field sensing and GPS.

  • robotic process automation

    Robotic process automation (RPA) software can adapt to changing circumstances, exceptions or new situations in real time without human help.

  • S

    sensor hub

    A sensor hub is a connection point for multiple sensors that uses a multipoint control unit (MCU), coprocessor or digital signal processor (DSP) to compile and process data gathered from those sensors.

  • smart grid sensor

    A smart grid sensor is a small, lightweight node that serves as a detection station in a sensor network.

  • smart sensor

    A smart sensor is a device that takes input from the physical environment and uses built-in compute resources to perform predefined functions upon detection of specific input and then process data before passing it on.

  • T

    thing (in the Internet of Things)

    A thing, in the context of the Internet of things (IoT), is an entity or physical object that has a unique identifier, an embedded system and the ability to transfer data over a network.

  • trillion-node network

    A trillion-node network refers to a near future state wherein trillions of devices, people, organizations, places and things are connected to the Internet. The implications of this ubiquitous connectivity and complexity hold both promise and risk that require the attention of multiple stakeholders.

  • U

    ubiquitous sensor network (USN)

    A ubiquitous sensor network (USN) is one that connects all possible sensors in a given network or environment which, theoretically, could be global.

  • unique identifier (UID)

    A unique identifier (UID) is a numeric or alphanumeric string that is associated with a single entity within a given system.

  • W

    WSAN (wireless sensor and actuator network)

    A wireless sensor and actuator network (WSAN) is a group of sensors that gather information about their environment and actuators, such as servos or motors, that interact with them. All elements communicate wirelessly; interaction can be autonomous or human-controlled.
