IoTBroker.cloud Java Client is an application that allows you to connect to the server using MQTT, MQTT-SN, AMQP or COAP protocols. IoTBroker.cloud Java Client gives the opportunity to exchange messages using protocols mentioned above. Your data can be also encrypted with TLS or DTLS.
Below you can find a brief description of each protocol that can help you make your choice. If you need to get more information, you can find it in our blog.
MQTT is a lightweight publish-subscribe based messaging protocol built for use over TCP/IP.
MQTT was designed to provide devices with limited resources an easy way to communicate effectively.
You need to familiarize yourself with the following MQTT features such as frequent communication drops, low bandwidth,
low storage and processing capabilities of devices.
Frankly, MQTT-SN is very similar to MQTT, but it was created for avoiding the potential problems that may occur at WSNs.
Creating large and complex systems is always associated with solving data exchange problems between their various nodes. Additional difficulties are brought by such factors as the requirements for fault tolerance, the geographical diversity of subsystems, the presence a lot of nodes interacting with each others. The AMQP protocol was developed to solve all these problems, which has three basic concepts: exchange, queue and routing key.
If you need to find a simple solution, it is recommended to choose the COAP protocol. The CoAP is a specialized web transfer protocol for use with constrained nodes and constrained (e.g., low-power, lossy) networks. It was developed to be used in very simple electronics devices that allows them to communicate interactively over the Internet. It is particularly targeted for small low power sensors, switches, valves and similar components that need to be controlled or supervised remotely, through standard Internet networks.
