Optimizing Edge Computing for Big Data Processing in Smart Cities

Abstract

The surge of big data and IoT in smart cities requires effective computational models to process massive amounts of real-time data. Edge computing emerges as an innovative solution by minimizing latency, improving security, and maximizing energy efficiency. This paper investigates the convergence of AI-based edge computing for big data processing through a study of four sophisticated algorithms: Federated Learning, TinyML, Edge-Optimized CNNs, and Adaptive Data Compression. Experimental analysis proved a decrease of 37% in latency, 42% increase in computational performance, and 29% decrease in energy usage than that of common cloud-based computation. In addition, a multilayered data fusion mechanism increased data quality by 21%, facilitating smart city decision-making. The analysis also compares contemporary techniques and expounds on how cloud-edge interaction could be a boon for improving the infrastructure in smart cities. Findings validate that edge computing improves real-time analytics, transportation safety, and sustainable resource management. Yet, security threats and scalability challenges need more investigation. Future research should concentrate on blockchain-based edge security models and energy-aware AI architectures to provide hassle-free smart city deployment. This research concludes that edge computing is the key to the next generation of smart urban infrastructure, encouraging efficiency, sustainability, and intelligent automation.
