The Internet of Things (IoT) paradigm aims to connect billions of devices, enabling wise and dynamic choice making across packages. However, the rapid expansion of IoT poses good-sized demanding situations for retaining quality of provider (QoS) requirements. This paper provides a detailed performance analysis and comparative analysis of Hypertext Transfer Protocol (HTTP) and Message Queuing Telemetry Transport (MQTT) protocol in oneM2M system; focusing on QoS aspects. HTTP, known as its simplicity and widespread use, facilitate client-server communication in many IoT applications. In contrast, MQTT, a lightweight messaging protocol, is optimized for low-bandwidth and high-latency environments, making it ideal for constrained devices and unwieldy networks reliability. We developed and implemented test scenarios incorporating homogeneous traffic and real-time data to assess the platform’s robust capabilities. Simulating realistic heavy load conditions and IoT network models, this study provides a thorough understanding of the strengths and limitations of the oneM2M platform in handling different traffic types and volumes The findings provide important insights into the scalability of the oneM2M platform, efficiency, and adaptability, which are important to ensure robust QoS in diverse IoT environments.
