This article introduces the fundamentals of the Internet of Things, explaining what IoT is, its distinguishing characteristics, its relationship with artificial intelligence, current market trends, and a detailed overview of common IoT communication protocols such as MQTT, CoAP, LwM2M, HTTP, LoRaWAN, and NB‑IoT.
MQTT and CoAP are lightweight IoT communication protocols with distinct architectures—MQTT uses a publish/subscribe model ideal for WAN scenarios and bandwidth‑constrained devices, while CoAP follows a request/response pattern suited for local networks and HTTP compatibility, and the article explains their differences and appropriate use cases.
This article reviews the most common IoT communication protocols—MQTT, CoAP, HTTP, XMPP, and SOAP—explaining their architectures, key features, message models, and practical differences to help developers choose the most suitable protocol for their IoT applications.
This article compares the lightweight CoAP/LWM2M protocol suite and the TCP‑based MQTT protocol, detailing their architectures, message structures, QoS levels, and typical IoT use cases, to help developers select the most suitable communication method for resource‑constrained devices.
SoftRadio is a remote online debugging system that enables end‑to‑end integration testing for NB‑IoT devices on Huawei’s OceanConnect platform, offering three‑layer functionality, REST‑based APIs, and CoAP over UDP simulation to improve development efficiency while remaining a test‑only feature.
This article explains the differences between MQTT and CoAP, two lightweight IoT communication protocols, and provides guidance on when to use each based on network conditions, architecture compatibility, and deployment scenarios.
