Logical Design of IoT

 

•Refers to abstract representation of the entities and processes. It includes Functional Blocks and Communication Models
•IoT functional Blocks-
ØIoT Device-to provide sensing,actuation,monitoring &control
ØCommunication-handles communication for IoT system
ØServices-like services for device monitoring,data publishing services,device discovery services etc
•Management-provides various functions to govern the IoT system
•Security-functions such as authentication, message and content integrity,and data security.
Applications-provides interace that user can use to control and monitor IoT system
IoTCommunication Models
•Request –Response---clients sends request to the server and server responds
•Publish-Subscribe---it involves publishers,brokers and consumers
•Push-pull-data producers push the data to queues and consumers pull the data from queue
Exclusive pair-fully duplex communication models.
Request respose model
Publish-subscribe model
Push-Pull model
Exclusive pair model

Defining IOT 2021

1-Internet of Things Definition and Few essential Features Internet of Things (IoT) term represents a general concept for the ability of network devices to sense and collect data from around the world, and then share that data across the Internet where it can be processed and utilized for various interesting purposes. The IoT is comprised of smart machines interacting and communicating with other machines, objects, environments and infrastructures. Few features Ø   The devices in IoT can be controlled remotely to perform the desired functionality. Ø   The information sharing among the devices then takes place through the network which employs the standard protocols of communication. Ø   The smart connected devices or ‘‘things’’ range from simple wearable accessories to large machines, each containing sensor chips. For instance, the Lenovo smart shoes contain chips which provide support of tracking and analyzing fitness data . Ø   Similarly, the electri...

Physical Design of IoT-1

  It includes IoT Devices and IoT protocols- Device consist of several interfaces for connection to other devices such as § I/O interface for sensors § Interfaces for Internet Connectivity § Memory and storage interfaces § Audio/video interfaces The sensed data s either communicated to other devices or servers/ cloud based storage. The generic block diagram of IoT deviceis as follows- • USB Host   - According to the  USB (Universal Serial Bus) standard a device is classified as either a  host  or a peripheral device. In the most common scenarios the  host , such as your PC, acts as a controller and the peripheral, such as a  USB  drive, responds to its commands. • Registered jack-45  (RJ45) refers to a cable termination specification that specifies physical male and female connectors and the pin assignments of wires-in telephone cables and other networks that use RJ45 connections. RJ45 connections are also known as data jacks....
