specific device. Currently, different types of agents for each of the IoT communication protocols
and data models have been developed. Some examples of these implementations are:

• IoTAgent-JSON: an adapter between HTTP/MQTT messaging (using JSON) and NGSI.

• IoTAgent-LWM2M: an adapter between the Lightweight M2M protocol and NGSI.
• IoTAgent-UL: adapts communication between HTTP/MQTT messaging (using UltraLight 2.0)
and NGSI.

• IoTAgent-LoRaWAN: manages the adaptation of communication between the LoRaWAN
protocol and NGSI.
