Abstract
While the Internet of Things (IoT) is transforming our daily lives, it still poses significant challenges in non-industrial use cases, such as smart homes or public facilities, where Low-power and Lossy Networks (LLNs) are commonly used. These technologies are cost-effective, but also raise important management issues. Software-Defined Networking (SDN) has emerged as a promising paradigm to address these challenges by introducing flexible and centralized network management. Although several SDN-based architectures have been proposed for IoT in non-industrial LLN environments, no comprehensive and focused survey has yet consolidated the recent advancements in this field. This paper discusses the need for SDN in IoT over LLNs, exploring how traditional approaches fall short and why SDN is essential for efficient network management. We also analyze existing SDN architectures for LLNs, propose an updated taxonomy, and identify research gaps and future challenges. This work serves as a valuable reference for researchers and practitioners aiming to adopt SDN on LLNs networks.
