Various researchers have defined different layers in an IoT System. Each layer has one or the other protocol. In each layer, one can find a number of protocols, forming a protocol family for a specific layer. These protocols are discussed in sequence corresponding to the different layers. The...
The choice of communication protocol depends on factors such as the nature of the devices, the network infrastructure, power constraints, and the specific requirements of the application. Here are some commonly used communication protocols in IoT....
All you need to know about the most used IoT protocols and their use. What is for example the link between protocol - Gateway - and the Cloud?
The IoT based devices are more susceptible to threats. So these security loopholes can be reduced by using the correct protocols. Communication protocols in IoT are types of communication that ensure the finest security toward the data being exchanged among the IoT connected devices. The connection ...
It is often used in combination with 6LoWPAN. To allow data exchange and facilitate control of the data pipeline, a messaging service is often leveraged within IoT deployments. Messaging protocols such as Message Queue Telemetry Transport (MQTT), Advanced Message Queuing Protocol (AMQP), and ...
CoAP, for its part, is preferred for gathering telemetry data transmitted from transient, low-power nodes like tiny field sensors. Despite fulfilling different needs, both protocols are fundamental in IoT and IIoT deployments, where fast and flexible data excha...
As far as the wireless IoT is the main concern, many different wireless communication technologies and protocols can be used to connect the smart device such as Internet Protocol Version 6 (IPv6), over Low power Wireless Personal Area Networks (6LoWPAN), ZigBee, Bluetooth Low Energy (BLE), Z...
Fig. 3presents some commonly used IoT protocols in the protocol stack as an first overview. A more detailed protocol stack for the protocols is given inFig. 4andFig. 5. Sign in to download hi-res image Fig. 3.IoT protocols in the protocol stack. ...
In this study, we review the fundamentals of IoT architecture and we thoroughly present the communication protocols that have been invented especially for IoT technology. Moreover, we analyze security threats, and general implementation problems, presenting several sectors that can benefit the most from...
All in all, there are mainly two types of protocols: network and data. This classification comes from the OSI (open systems interconnection) model, widely used in IT communication networks. Below you can get a general understanding of the main IoT network protocols. Bluetooth: This pro...
