Scalable IoT Networking: Energy-Efficient Communication Protocols, Lightweight Security Frameworks, and Resilient Infrastructure Design

This research work will focus on the Internet of Things (IoT) is revolutionizing both industries and everyday life by facilitating seamless connections among billions of diverse devices. As IoT networks expand, the demand for robust and scalable communication protocols becomes crucial. Protocols like MQTT, CoAP, and LPWAN technologies (e.g., 6LoWPAN) are extensively used due to their lightweight nature, which supports efficient message exchange and interoperability across various device types and network structures. A significant challenge remains in energy-efficient data transmission, as many IoT devices have limited power resources. Implementing low-power wireless protocols and optimized routing strategies is vital to extend device longevity while ensuring reliable connectivity. Security is another critical issue, given the widespread interconnection of endpoints and the sensitive nature of the data being transmitted. Traditional security frameworks often do not suit resource-limited IoT devices, necessitating the creation of lightweight cryptographic protocols and adaptive security measures tailored to IoT settings. This paper reviews recent advancements in scalable IoT networking, concentrating on communication protocol design, energy-efficient data transmission methods, and emerging security challenges, and it highlights research directions for developing resilient, secure, and scalable IoT infrastructures.
