A Comprehensive Framework for Many-Objective Resource Scheduling and Carbon-Aware Orchestration in Distributed Fog-Cloud Ecosystems

The rapid proliferation of Internet of Things (IoT) devices and the subsequent data deluge have necessitated a paradigm shift from centralized cloud computing to distributed architectures encompassing fog and edge computing. As these environments evolve, the complexity of task scheduling has transitioned from simple multi-objective optimization to many-objective optimization, where conflicting goals-such as energy efficiency, reliability, deadline constraints, cost, and carbon footprint-must be balanced simultaneously. This research article provides an extensive investigation into the theoretical underpinnings and practical applications of many-objective evolutionary algorithms and swarm intelligence within the context of fog-integrated cloud environments. By synthesizing contemporary research on diversity assessment, grid-based evolutionary strategies, and carbon-aware Kubernetes-native scheduling, this study proposes a holistic framework for managing scientific workflows and big data pipelines. The analysis explores the nuances of balanceable fitness estimation, clustering-based selection mechanisms, and the integration of data analytics for congestion management. Special emphasis is placed on the emerging necessity of carbon-aware scheduling to mitigate the environmental impact of large-scale distributed systems. The findings suggest that while traditional meta-heuristics are effective for low-dimensional problems, the scalability of many-objective approaches, such as those implemented in the PlatEMO platform, is essential for the next generation of smart grid and industrial IoT applications.
