The knowledge points of this article "what are the 15 standard protocols of the Internet of things" are not quite understood by most people, so the editor summarizes the following contents, with detailed contents and clear steps, which can be used for reference. I hope you can gain something after reading this article. Let's take a look at this article "what are the 15 standard protocols of the Internet of things?"

1. Bluetooth

Bluetooth is one of the most widely used wireless technologies in close range. You can get Bluetooth applications quickly, providing you with wearable technology to pair with smart gadgets. The recently introduced Bluetooth protocol in IoT protocol is BLE or Bluetooth Low-Energy protocol. It will provide the range of traditional Bluetooth and the advantage of lower power consumption.

You must keep in mind that BLE is not designed to transfer large files, it works perfectly with a small amount of data. That's why Bluetooth is leading the Internet of things protocol in this century. The newly invented Bluetooth Core Specification 4.2 adds an innovative Internet protocol support profile. It allows Bluetooth Smart Sensor to access Internet directly through 6LoAPAN.

2. WiFi

For the integration of the Internet of things, WiFi is the preferred choice of many electronic designers. This is because of the infrastructure it carries. It has fast data transmission rate and the ability to control a large amount of data.

WiFi's extensive WiFi standard 802.11 enables you to transmit hundreds of megabits of data in one second. The only drawback of this IoT protocol is that it may consume too much power from some IoT applications. Its scope is about 50 m, and with the development of Internet protocol standards, it also includes IoT Cloud infrastructure access. The frequency is in the 2.4GHz and 5GHz bands.

3. ZigBee

Like Bluetooth, ZigBee has a large user base. In the Internet of things protocol, the design of ZigBee is more industry-oriented and less consumer-oriented. It usually runs at the frequency of 2.4GHz. This is ideal for industrial sites that usually transfer data at a small rate between houses or buildings.

ZigBee and popular ZigBee Remote Control are well-known IoT security protocols, which provide secure, low-power, scalable solutions and a large number of nodes. ZigBee 3.0 has promoted the protocol to a single standard. It becomes more convenient.

4. MQTT IoT

MQTT IoT is a message protocol and the full form is Message Queue Telemetry Transport. It was developed by Arlen Nipper (Arcom) and Andy Stanford-Clark (IBM) in 1999. It is mainly used for monitoring from remote areas of IoT. The main task of MQTT is to obtain data from many electronic devices.

It also transmits them to It communications or infrastructure. For the MQTT IoT protocol, the hub-and-spoke architecture is basically common. It works on top of TCP and provides reliable and simple data streams.

This MQTT protocol consists of three core components or mechanisms: subscribers, publishers, and agents. The publisher's job is to generate data and transfer it to the subscriber with the help of the agent. It is the broker's job to ensure safety. It is achieved by checking and re-examining the authorizations of subscribers and publishers.

This protocol is the preferred scheme for all devices based on the Internet of things, and these devices can also provide sufficient information routing functions to cheap, low-memory power and small devices with the help of low-bandwidth and vulnerable networks.

5. CoAP

CoAP or Constrained Application Protocol, an Internet productivity and utility protocol, is developed primarily for limited smart devices. CoAP is designed to use it between devices that have the same restricted community. It includes regular nodes and devices on Internet, as well as different restricted networks and devices connected to Internet.

The IoT system based on HTTP protocol can be perfectly combined with CoAP IoT network protocol. It uses the protocol UDP to implement lightweight data. Like HTTP, it uses the Restful architecture. It is also used as a basic program within mobile phones and other social communities. CoAP helps disambiguate through HTTP get, up, delete, and placed policies.

6. DDS

In the Internet of things protocol, the Internet of things messaging protocol (DDS or data distribution service) is a high-performance, scalable and real-time machine-to-machine communication standard. The data distribution service DDA is developed and designed by OMG or the object management group. With the help of DDS, you can transfer data on low-footprint devices and cloud platforms.

The data distribution service consists of two important layers. These are DCP and DLRL. DCP or data-centric publish subscriptions work by passing information to subscribers. The DLRL or data local reconstruction layer does its work by providing an interface to the data-centric public subscription function.

7. NFC

NFC in the Internet of things protocol makes full use of secure two-way communication links. NFC IoT communication protocol is suitable for smart phones.

NFC or near Field Communications (Near Field Communication) allows customers to connect to electronic devices, use digital content, and conduct contactless payment transactions. The basic work of NFC is to extend the "contactless" card technology. By enabling devices to share information, it can work within 4cm (between devices).

8. Cellular

There are many Internet of things applications that may need to operate over longer distances. These Internet of things applications can take advantage of cellular communication functions such as GSM / 3G / 4G. Cellular is one of the IoT communication protocols that can send or transmit large amounts of data.

The cost of sending large amounts of data can also be high. Cellular networks not only require high costs, but also require high power consumption in multiple applications. This Internet of things protocol is amazing for low-bandwidth sensor-based data projects. This is because they can send a very small amount of data or information on the Internet.

It includes a real small CELLv1.0 low-cost development board. It also has a series of shielding layers for connecting plates (so that you can use them on Arduino and Raspberry Pi platforms.) The key product here is SparqEE.

9. AMQP

The Advanced message queuing Protocol, or AMQP, is an application layer protocol. It is basically message-oriented and is designed for middleware environments. AMQP IoT messaging protocol has been recognized by international standards. The processing chain of the AMQP IoT protocol contains three required components, namely, Exchange, message queuing and binding.

The Exchange part works by getting the message and queuing it. The task of message queuing is to store messages, which stores information until the client application securely develops the message. The job of the binding component is to declare the connection between the Exchange component and the message queuing component.

10. LoRaWAN

LoRaWAN or remote wide area Network (Long Ranged Wide Area Network) is one of the IoT protocols for wide area networks. The LoRaWAN IoT network protocol is specifically designed to support large networks with millions of low-power devices. Smart City uses this protocol.

LoRaWAN is also known in many industries for its protective two-way communications, including low-cost mobile communications. The frequency of LoRaWAN may vary from network to network. The data rate of the Internet of things protocol is between 0.3 and 50 kbps. In urban areas, LoRaWAN ranges from 2 km to 5 km. In the suburbs, the Internet of things agreement covers a range of about 15 kilometers.

11. RFID

Radio frequency identification of RFID works with the help of wireless technology. It uses electromagnetic fields to identify objects. Short range radio frequency identification is about 10 centimeters. But the remote radio frequency can reach 200 mm.

Active tags are usually used in ARAT or active card reader active tagging systems. These activity tags are awakened by any inquiry signal (a signal from the active card reader). The best part of the RFID Internet of things protocol is that they don't need any power.

12. Z-Wave

The Z-Wave IoT protocol provides you with low-power RF or RF communications. We usually use them in home automation applications. Sensors, lamp controllers, etc., are low power radio frequencies. This low-latency technology also has more features to block wireless technologies such as WiFi. It can work in a frequency band lower than 1GHz.

Designers focus on the simple and rapid development process of the Internet of things protocol. They are trying to simplify the setup of the Z-Wave IoT protocol. The frequency of Z-Wave Internet of things protocol is 900MHz, and the range is about 30-100m. It provides you with cloud access and requires a bridge. The data rate of the protocol is 40-100kbit / s.

13. Sigfox

Sigfox is recognized as one of the best alternative technologies with cellular and WiFi properties. Because the Sigfox IoT protocol is developed and designed for M2M applications, only low-level data can be sent. By using UNB or ultra-narrowband, Sigfox can maintain a speed of 10 to 1000 bits per second to transmit low data. It consumes only 50 microwatts of power.

The frequency of the Internet of things connection protocol Sigfox is 900MHz. In rural environments, the coverage of the Sigfox IoT protocol ranges from 30 km to 50 km. In urban areas, the scope of this agreement is 3-10 km.

14. Thread

One of the latest protocols of the Internet of things is the IoT security protocol Thread. The inventor of Next designed this protocol. In home automation applications, this Internet of things protocol is now increasing its scope of use. This is the IPv6 network protocol based on IP, which is based on 6LowPAN.

It is mainly used to supplement the WiFi within the family. The agreement is royalty-free. The protocol supports mesh networks within IEEE802.15.4 's transceivers. It can handle about 250 nodes as well as encryption and authentication. The frequency of Thread Internet of things protocol is 2.4GHz (ISM) and can cover 10-30m.

15. EnOcean

In the Internet of things connection protocol, EnOcean has an innovative transformation. It is a wireless sensing and energy collection platform. It is ideal for designing devices that need to respond to different situations, such as temperature changes, lighting, and other irregularities.

At present, most of the applications of the IoT protocol are in the fields of transportation, home automation, industrial automation and logistics. The frequency of EnOcean IoT protocol is 315 MHZ,868 MHz and 902MHz. It provides you with access to Cloud, covering 300m outdoor and 30m indoor.
