A Survey on Security in Data Transmission Using Wireless Communication Methods for IoT Edge Devices
V. Maruthi Prasad, B. Bharathi · 2025
Establishing data transfer in IoT applications hinges on communication standards. Selecting a communication protocol proves challenging due to its reliance on the IoT system's characteristics and its data transmission infrastructure. The evolution of IoT applications necessitates ubiquitous and instantaneous connectivity infrastructure. Over the past decade, researchers’ requirements have spurred the development and utilization of a diverse array of communication protocols. Among the plethora of wireless communication methods and protocols (such as MQTT, HTTP, CoAP, etc.), wireless IoT takes precedence. However, none of these protocols can satisfy every criterion (such as ecological friendliness, safety, service quality, etc.). This study offers a comparative analysis of “popular communication protocols used in IoT scenarios,” presenting various messaging protocols by contrasting their primary features across a wide spectrum. Additionally, it conducts a comparative study based on interconnected characteristics to comprehensively understand their strengths and weaknesses. The ability to interconnect devices is pivotal in the Internet of Things, forming a vast network of interconnected entities—ranging from objects to individuals—collaborating to gather and disseminate data. Often, data collection serves to automate processes or facilitate decision-making. Diverse communication and network protocols cater to varied data types and applications. Based on the findings of this detailed analysis, users can make informed decisions on optimal implementation strategies for different Internet of Things systems. Notably, AMQP, CoAP, and DDS protocols exhibit greater security compared to HTTP, MQTT, and XMPP, although HTTP protocol demands the highest power and energy resources.
