    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
