Now the world has been adopting in new invigorating technologies to make human works to do as quickly possible and make it easier. yup! Now let we are going to take look at one  of that technology that the Internet Of Things

What is Internet of Things

      The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

thing in the internet of things can be a person with a heart monitor implant, a farm animal with a biochip transponder, an automobile that has built-in sensors to alert the driver when tire pressure is low or any other natural or man-made object that can be assigned an Internet Protocol (IP) address and is able to transfer data over a network.

IOT protocols

Nowadays, there is a range of objects around us that are capable of collecting, sending and processing data to the other servers and other applications. The IoT Protocols is such a system that will transfer data in the online. But it will transfer data only then when the communication network between the two connected devices is safe.

We can divide the internet of things protocols into two basic types: IoT Network Protocols and IoT Data Protocols.

   One of the most broadly used wireless technologies of short-range is Bluetooth. You can quickly get Bluetooth apps that offer you wearable technology for pairing up with the smart gadgets. The recently introduced Bluetooth protocol among the IoT protocols is BLE or Bluetooth Low-Energy protocol. It will afford the range of conventional Bluetooth in combined with lower power consumption supremacy

  • Standard: Bluetooth 4.2 core specification
  • Frequency: 2.4GHz (ISM)
  • Range: 50-150m (Smart/BLE)
  • Data Rates: 1Mbps (Smart/BLE)

  •  WiFi

          For IoT integration, WiFi is a favored choice according to many electronic designers. It is because of the infrastructure it bears. It has quick data transfer rates along with the aptitude to control a large quantity of data.

    • Standard: Based on 802.11n (most common usage in homes today)
    • Frequencies: 2.4GHz and 5GHz bands
    • Range: Approximately 50m
    • Data Rates: 600 Mbps maximum, but 150-200Mbps is more typical, depending on channel frequency used and number of antennas (latest 802.11-ac standard should offer 500Mbps to 1Gbps)

    The only own drawback of this IoT protocol is it can consume excessive power for some of the IoT Application


          Just like Bluetooth, there is a vast user base of ZigBee. Among the internet of things protocols, ZigBee is designed more for the industrials and less for the consumers. It usually operates at a frequency of 2.4GHz. This is ideal for the industrial sites where data is generally transferred over small rates amongst home or a building.
    ZigBee and the popular ZigBee Remote Control are popular as famed IoT Security Protocols for supplying secure, low-power, scalable solutions along with high node counts. The ZigBee 3.0 has taken the protocol to a single standard.

    • Standard: ZigBee 3.0 based on IEEE802.15.4
    • Frequency: 2.4GHz
    • Range: 10-100m
    • Data Rates: 250kbps

    MQTT IoT

          MQTT IoT is a message protocol and full form is Message Queue Telemetry Transport. The principal task that MQTT does is obtaining data from so many electrical devices.  It works on top of the TCP for supplying reliable yet simple streams of data.  

    This MQTT protocol is made of three core components or mechanisms: Subscriber, Publisher, and Broker. The work of the publisher is generating data and transmitting the data to the subscriber with the help of the broker. Ensuring security is the job of the broker. It does it by checking and rechecking the authorization of the subscribers and the publishers.


        CoAP is designed to enable simple, constrained devices to join the IoT even through constrained networks with low bandwidth and low availability. It is generally used for machine-to-machine (M2M) applications such as smart energy and building automation.

    The CoAP or Constrained Application Protocol, an internet productivity and utility protocol, is mainly developed for the restricted smart gadgets. The design of CoAP is for using it among the devices that have an identical restricted community. It includes general nodes and devices on the internet and different restrained networks and devices that are joined on the internet.


       Amongst the internet of things protocols, the IoT Messaging Protocols – DDS or Data Distribution Service is a standard for high-performance, expandable and real-time machine-to-machine communication. The Data Distribution Service – DDA is developed and designed by OMG or Object Management Group. With the help of DDS, you can transfer data both in the low-footprint devices and with the Cloud platforms.

    The Data Distribution Service includes two significant layers. Those are the DCPS and the DLRL. The DCPS or Data-Centric Publish-Subscribe works by delivering information to the subscribers. The DLRL or Data-Local Reconstruction Layer does its job by providing an interface to the Data-Centric Public-Subscribe functionalities. 


          The NFC or Near Field Communication allows the clients to connect to the electronic devices, to use digital contents and to do the contactless payment transaction. The essential work of NFC is to expand the “contactless” card technology. It works within 4cm (between devices) by enabling the devices for sharing information.

    IoT vs IIoT

         The Internet of Things brings the physical world to the digital world, vastly expanding what information technology can achieve. By connecting physical assets with the digital sphere using sensors and actuators, we can electronically monitor and manage our ‘things’.

    IIoT stands for the Industrial Internet of Things – it applies IoT technologies to the manufacturing industry. Also referred to as the Industrial Internet, IIoT focuses on improving connectivity, efficiency, scalability, time savings and cost savings for industrial organisations, and will sometimes be used interchangeably with Industry 4.0.

         The difference between IoT & IIoT
    1. Served applications IoT can be used in all verticals. That means IoT is not only used in Industry applications but also in personal or research-oriented cases. IIoT can’t be used in all verticals. Moreover, it means Industrial IoT is an industry application-specific platform.
    2. Sensors Used In IoT eventually, sensors can be of any kind. For instance Moisture, Motion, Heart Rate monitoring, Gas sensors or any other sensor that can be accessed via the cloud. As a matter of fact, the sensors used in Industrial IoT are those sensors mostly used in different industries. For instance Heat, Temperature, Flow, Wind, Light, Vibration &Pressure sensors.
    3. Types of Cloud technology used Generally, The IoT Uses Public Cloud. Consequently, Industrial IoT uses Private Cloud. Comparatively, IIoT is secure than IoT.
    4. Cybersecurity IoT is not much secured as compared to Industrial IoT. In other words, IoT is used mostly as open access. Moreover,Industrial IoT maintains very robustly Cyber Security. In fact, IIoT is implemented in a very important sector of the industry.
    5. Operation Safety Despite used in different applications, operation safety in IoT is always not very high. In Industrial IoT operation safety is the most important thing. Whereas a lack of safety measures will lead to Blast/Property damage/Human Death.
    6. Examples For example, We use IoT in agriculture or Healthcare or Banking For example, IIoT can be used in Oil or Gas sector within a particular industry.

    IoT the term refers to the connection of devices (the Things) through the internet so they can collect and share data without human assistance.

    Industrial Internet of Things (IIoT) refers to the use of Internet of Things (IoT) technologies in manufacturing and related industries like agriculture, gas and oil, utilities, and transportation to create smart, self-regulating systems.The Industrial Internet of Things is opening up a new era of economic growth and competitiveness, this will transform companies and countries. We are looking at a future where the intersection of people, data and intelligent machines will have high reaching impacts on the productivity, efficiency and operations of industries around the world.
