Internet of things (IOT) is a field of communication technology development. It is estimated that the annual growth rate of the Internet of things market will reach 457 billion by 2020. According to statistics, by 2025, the number of IOT devices will reach 75 billion. The global demand for communication protocols is increasing, so it is necessary to maintain the security of communication protocols. Therefore, in order to protect the security of the protocol, there are many ways to do this. It depends entirely on the network structure and communication protocol.
Many of the top companies work with leading IOT providers in the industry. The level of communication is not only based on the network, but also requires us to observe the range of objects around us. Therefore, I listed the Internet of things protocols based on standard communication level.
There are two modes of IOT protocol: IOT data protocol and IOT network protocol. These two protocols depend on the scope and type of data level. On this basis, the corresponding protocol is designed.
1. Level based communication attention
It is a layer based protocol called advanced message queuing protocol (AMQP). It is basically a data communication oriented protocol designed for middleware based environment. The agreement has been recognized by international standards. AMQP IOT protocol is divided into three essential components: exchange, message queuing and binding. The first is called message, which receives messages or data and queues them for processing. It helps to store data in queues until the data is developed by the client application. Binding components build a bridge between exchange and message queue components.
2. Recognition by remote observation
Radio frequency identification (RFID) works with wireless technology. To identify objects, it uses electromagnetic fields. The shortest distance is cm and the longest distance is 200m.
To activate, radio frequency identification (RFID), a tag called active reader activation (ARAT), has been in use. It activates the tag with any signal generated by the active reader. The advantage of using this protocol is that it does not consume any connected power.
3. Impact of energy route flow
The enocean protocol is designed to collect energy through wireless technology. It is mainly used in the building automation system sector, but also used in transportation, logistics and some industries. It depends on various states, such as temperature, light and other unstable conditions. It carries a bandwidth of 315 MHz and 908 MHz. Even you can access it from the cloud.
4. Wi Fi is a very popular technology
Wi Fi is a popular protocol that aims to communicate in a faster and more compact way. Data transmission through Wi Fi devices can control a large amount of data. The design of infrastructure is humanized.
The Wi Fi standard of Internet of things is 802.11ax, and the frequency is 2.4GHz and 5GHz. The ability to transmit data has become faster, allowing data to be transmitted at hundreds of megabits per second. The disadvantage of the Internet of things protocol is the power cost of transferring data over a network based on the protocol you choose.
5. Threads help to interconnect the network of nodes
It is a trend protocol in the Internet of things industry. It is designed by thread groups. It is a low-power wireless mesh network protocol. It has been used in home based applications. The protocol is now busy with many applications. It is designed based on IPv6 network protocol. It is based on the mesh network standard, and the standard rate is 802.15.4. It connects hundreds of low-power devices through the cloud.
It can withstand 250 nodes as well as encryption and authentication. It needs a frequency of 2.4GHz bandwidth, which can be controlled in about 10-30m.
6. Low frequency operation
The protocol used to work in the Internet of things at low frequencies is called Z wave. Since sensors, lamp controllers and other components work under low power RF, they can be used in home applications. This low latency technology has many features, such as shielded wireless technology and Wi Fi. It works at frequencies below 1GHz.
The protocol is designed with a simple and fast architecture. The protocol adopts Z-Wave design and is easy to operate. Its bandwidth is 900MHz, ranging from 30-100m, and can even be accessed through the cloud. The data transmission speed is over 40-100kbit / s.
7. Remote communication
If the data transmission distance depends on a wider range of applications, lorawan or remote Wan is the suitable protocol for the network. It is designed to run in low-power devices and supports multiple networks based on the standard.
It works in low-level mobile communication. It has been used by many industries to protect two-way communication. The frequency of this protocol varies with distance. The Internet of things protocol runs in the range of 0.3 to 50 Kbps. In urban areas, it uses a distance of 2 km to 5 km, while the suburban location is about 15 km to manipulate data.
At present, many protocols have been designed for the Internet of things according to the needs of users. The agreement was chosen based on the data I mentioned above. This may give you some confirmation about your data preferences so you can choose based on your usage. Therefore, IOT protocols are based on factors such as bandwidth, range, power consumption and protocol nodes. I hope the above data on the Internet of things industry trends and the most widely used application development protocols will help you decide the protocol according to your needs.
