REST is a scalable architecture which allows for things to communicate over Hypertext Transfer Protocol and is easily adopted for IoT applications to provide communication from a thing to a central web server. [35] MQTT is a publish-subscribe architecture on top of TCP/IP which allows for bi-directional communication between a thing and a MQTT ...
The controller performs tasks, processes data and controls the functionality of other components in the sensor node. While the most common controller is a microcontroller, other alternatives that can be used as a controller are: a general purpose desktop microprocessor, digital signal processors, FPGAs and ASICs.
Decentralized Internet of things, or decentralized IoT, is a modified IoT which utilizes fog computing to handle and balance requests of connected IoT devices in order to reduce loading on the cloud servers and improve responsiveness for latency-sensitive IoT applications like vital signs monitoring of patients, vehicle-to-vehicle communication ...
If a centralized architecture is used in a sensor network and the central node fails, then the entire network will collapse, however the reliability of the sensor network can be increased by using a distributed control architecture. Distributed control is used in WSNs for the following reasons: Sensor nodes are prone to failure,
Service Layer for multivendor interoperability. The architecture standardised by oneM2M defines an IoT Service Layer, i.e. a vendor-independent software Middleware between processing and communication hardware and IoT applications providing a set of functions commonly needed by IoT applications.
Ambient IoT, from ambient and Internet of things, is a concept originally coined by 3GPP [1] that is used in the technology industry referring to an ecosystem of a large number of objects in which every item is connected into a wireless sensor network using low-cost self-powered sensor nodes.
Adopted by Gen Z and Gen Alpha, it gained new prominence in 2024, according to Oxford, as a term used to capture concerns about the impact of consuming excessive amounts of "low-quality online ...
It is intended to help secure Internet of things (IoT) devices built on system-on-a-chip (SoC) processors. [175] It was introduced to increase security where a full trusted execution environment is too large or complex. [176] The architecture was introduced by Arm in 2017 at the annual TechCon event.
