Abstract
The rapid proliferation of Internet of Things (IoT) ecosystems has intensified the demand for efficient, scalable, and secure data processing architectures, positioning IoT edge gateways as a critical component in modern distributed systems. These gateways act as intermediaries between edge devices and cloud infrastructures, enabling real-time data processing, protocol translation, and localized decision-making. This paper presents a comprehensive review of IoT edge gateway models, methods, and emerging applications, with a strong emphasis on intelligent processing, security integration, and software engineering perspectives. The study systematically analyzes recent advancements in edge gateway architectures, including virtualization-based models, containerized microservices, AI-enabled gateways, and software-defined edge frameworks. Key findings reveal a shift from traditional rule-based processing toward adaptive, AI-driven edge intelligence, enhancing latency reduction, bandwidth optimization, and security enforcement. The review also identifies critical challenges such as resource constraints, interoperability issues, and security vulnerabilities in distributed edge environments. The primary contribution of this work lies in synthesizing recent research trends, identifying methodological gaps, and proposing future research directions that integrate edge intelligence with secure software engineering practices and DevSecOps pipelines.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
