This survey provides a detailed examination of the integration of machine learning (ML) techniques in intrusion detection systems (IDS) tailored for wireless sensor networks (WSNs). With the growing importance of WSNs across various applications such as environmental monitoring and the development of smart cities, ensuring their security from potential intrusions is of utmost significance. The paper initiates by elucidating the foundational concepts underpinning WSNs and the associated security challenges. This is succeeded by discussing the diverse machine learning paradigms and their pertinence in the WSN domain. The core of this survey is dedicated to an in-depth analysis of the various ML methodologies utilized in intrusion detection for WSNs—covering supervised, unsupervised, and semi-supervised techniques. A meticulous comparative study highlights each method's strengths, limitations, and specific use cases. Furthermore, the paper brings to light the challenges faced when integrating ML within WSNs, with a particular emphasis on issues related to privacy. On a prospective note, the research navigates into the future trends in the realm of WSN security. Here, the promise of enhanced ML algorithms, the potential of hybrid models, and the impact of upcoming technological advancements on the synergy between WSNs and ML are explored. The insights from this review not only validate the game-changing role of ML in bolstering WSN security but also pave the way for further inquiries and innovations in the domain.
