Internet of Things Architecture

Leaf Device A node placed in outer part of routing area of a
network. It is referred to as leaf with reference to the
routing tree, where links are the branches and the outer
nodes of the network are the leaves of the tree.

Local Storage Special type of Resource^ that contains information
about one or only a few Entities in the vicinity of a
device.

Internal

Location
Technologies

All technologies whose primary purpose is to establish

and communicate the location of a device e.g. GPS,

RTLS, etc.

Internal

Look-up In contrast to Discovery, Look-up^ is a Service^ that
addresses exiting known Resources using a key or
Identifier.

M2M (also referred
to as machine to
machine)

―The automatic communications between devices

without human intervention. It often refers to a system

of remote sensors that is continuously transmitting data

to a central system. Agricultural weather sensing

systems, automatic meter reading and RFID tags are

examples.‖

Microcontroller ―A microcontroller^ is a small computer on a single
integrated circuit containing a processor core, memory,
and programmable input/output peripherals. Program
memory in the form of NOR flash or OTP ROM is also
often included on chip, as well as a typically small
amount of RAM. Microcontrollers are designed for
embedded applications, in contrast to the
microprocessors used in personal computers or other
general purpose applications.
Microcontrollers are used in automatically controlled
products and devices, such as automobile engine
control systems, implantable medical devices, remote
controls, office machines, appliances, power tools, and
toys. By reducing the size and cost compared to a
design that uses a separate microprocessor, memory,
and input/output devices, microcontrollers make it
economical to digitally control even more devices and
processes. Mixed signal microcontrollers are common,
integrating analog components needed to control non-
digital electronic systems‖.

Network-based
resource

Resource hosted somewhere in the network, e.g., in

the cloud.

Next-Generation
Networks (NGN)

―Packet-based network able to provide

telecommunication services and able to make use of

multiple broadband, QoS-enabled transport

technologies and in which service-related functions are

independent from underlying transport-related

technologies‖
