A Review of Secure and Efficient Data Transmission in IoT Systems: Advances and Open Research Challenges

Abstract

The prompt reproduction of the Internet-of-Things (IoT) is used to convert communication networks by connecting billions of diverse devices, ranging from wearable sensors to made-up models. Ensuring the security and efficiency of data transmission in IoT communication networks poses a crucial challenge due to resource constraints, dynamic topologies, and diverse communication protocols. This review paper introduces a methodological analysis of state-of-the-art methods of secure IoT systems in communication networks, consisting of cryptography, approaches based on blockchain, and systems-based intrusion detection. This review paper is also used to examine some strategies for improving data efficiency, like edge computing, data aggregation, and AI-assisted routing protocols. Through estimating current solutions and summarizing such limitations, this review paper aims to differentiate research gaps. This review paper provides a powerful roadmap for researchers and practitioners seeking to build and design strong IoT systems able to support the shining future for the design of smart cities, healthcare systems, and commercial automation as well.
