APPLICATION LAYER

Node APP: Application of single IoT

terminal equipment and it runs on a

single IoT terminal equipment.

Co APP: Coordination applications

among multiple equipment, it runs

on the gateway of a cell network and

is responsible for the coordination

and optimization of terminal

equipment under the cell network.

Cloud APP: Responsible for data

storage, calculation and display.

Presentation APP: Running on the

PC terminal or mobile terminal,

responsible for the final display of

the IoT application system.

Software Defined Terminal

The Terminals provide

high performance

hardware with a lite-

weighted operation

system embedded.

The OS acts as a

platform that has access

to the hardware.

Applications can be

applied on the OS to

define the function of
