A set of communication protocols that use electromagnetic fields that allow two devices to communicate with each other at a distance of four centimeters. NFC-enabled devices act as ID key cards and are often used for contactless mobile payments, ticketing, and chip cards. Compared to the other IoT network protocols listed here, Bluetooth tends to jump frequency and usually has a shorter range. However, it has gained a large user base due to its integration with modern mobile devices – smartphones and tablets, to name a few – as well as wearable technologies such as wireless headphones. Since many different devices and systems can use Bluetooth, it is ideal for promoting interoperability and enabling communication between very different systems and applications. The Internet protocols used generally vary by layer. Therefore, an IoT ecosystem could have multiple protocols, with different protocols allowing communication at different levels and connecting certain protocols between layers, said Scott Young, senior infrastructure research advisor at Info-Tech Research Group. IoT devices are typically connected to the internet through an Internet Protocol (IP) network. However, devices such as Bluetooth and RFID allow IoT devices to connect locally. In these cases, there is a difference in performance, scope, and storage. Connecting over IP networks is relatively complex, requiring more memory and performance from IoT devices, while range is not an issue. On the other hand, non-IP networks require comparatively less power and storage, but have a limited range. An AMQP is an open standard application-layer protocol used for transactional messages between servers.
Bluetooth is a protocol used for communication over short distances and exchanging small amounts of data for personal products such as smart watches or wireless speakers. That being said, it is still used in some industries. For example, 3D manufacturing and printing rely on HTTP because of the large amounts of data they can publish. It allows PC connection to 3D printers in the network and printing of three-dimensional objects. Multiple IoT protocols are available, each offering specific features or combinations of features that make it preferable over other options for specific IoT deployments. And so on. Again, in an ideal IoT system, each of these protocols should be compatible with all the other protocols in that layer. When building a network, technologists can choose from several communication protocols to serve their IoT ecosystem. Among the most common are the following.
It is widely used in consumer electronics because it can be easily adapted to mobile devices, it is really inexpensive and has a long battery life. IoT protocols can be divided into two categories: IoT network protocols and IoT data protocols. Data protocols primarily focus on exchanging information, while network protocols provide methods for connecting IoT edge devices to other edge devices or the internet. Each category contains a set of protocols, each with its own unique characteristics. We will then look at them. This protocol is at the origin of data communication for the World Wide Web (WWW), so it is logically used in the world of IoT. However, it is not optimized for the following reasons: Since its introduction, XMPP has been widely used as a communication protocol. Over time and with the advent of a lightweight XMPP specification: XMPP-IoT, it has been used in the context of the Internet of Things. As an open and community-supported standard, XMPP IoT`s strengths lie in its addressing and scalability capabilities, making it perfect for consumer-facing IoT deployments. These are IoT data protocols: AMQP, CoAP, DDS, MQTT, HTTP, TCP, WebSocket. Again, one of the goals of organizing all these components into layers is to focus on the different functions of the different protocols.
For example, the application protocols included in all of the above templates transform/present data so that a typical user can understand it. As IoT experts, we believe these are the most well-known wireless protocols in the IoT space. While DDS is not a typical IoT solution, it still finds application in some industrial implementations of the Internet of Things, such as air traffic control, intelligent network management, autonomous vehicles, transportation systems, robotics, power generation, and healthcare services. Overall, DDS can be used to manage data exchange between lightweight devices and connect large networks of high-performance sensors. It can also send and receive data from the cloud. Zigbee is a mesh network protocol designed for construction and home automation applications and is one of the most popular mesh protocols in IoT environments. Zigbee is a short-range, low-power protocol that can be used to extend communication across multiple devices. It has a range greater than BLE, but it has a data rate lower than BLE. Overseen by the Zigbee Alliance, it offers a flexible and self-organizing mesh, ultra-low power consumption and an application library. The wireless communication protocol in IoT is the set of rules for the exchange of data between electronic devices.
Bluetooth, ZigBee, LoRa, NBIoT, WiFi and Thread are the most commonly used protocols. Let`s take a deep look at each protocol. Z-Wave is an impressive IoT protocol. However, like ZigBee, it is best to use it at home and not in the business world. This type of protocol is used to connect low-power IoT devices. You can connect to user-side hardware without needing an Internet connection.
