Special Issue Information

Dear Colleagues,

In recent years, Internet of Thing (IoT) devices have been vastly proliferated into many aspects of everyday life. The introduction of increasingly more capable devices makes them naturally central in the Edge and Fog computing paradigms. Exploring their interactions, collaboration, and communication capabilities is now a relevant research topic that enables the maximization of their use in several different scenarios.

Many problems, such as dealing with their heterogeneity, communication, computing, and storage capabilities, stem from the need to explore such devices in those contexts. Thus, new research is needed to find solutions for the various challenges resulting from the utilizations of devices such as Edge and Fog nodes. This Special Issue welcomes original research and review articles on all aspects of the use of IoT devices in the context of Edge and Fog computing paradigms. Topics of interest include, but are not limited to, the following areas:

  • IoT devices for Edge computing;
  • IoT devices for Fog computing;
  • Computational offloading;
  • Programming paradigms for IoT devices;
  • Protocols for distributed computing with IoT devices;
  • Ad-Hoc networks and IoT devices;
  • Abstraction of heterogeneous IoT devices;
  • Resource reservation in IoT devices;
  • Scheduling in IoT devices;
  • Parallel processing in IoT devices;
  • Coalitions of IoT devices;
  • Performance of IoT devices in the context of Edge and Fog;
  • QoS management in IoT devices;
  • Orchestration of IoT devices;
  • Security issues in IoT devices;
  • Embedded systems.

Abstract
Distributed Kubernetes clusters provide robust solutions for geo-redundancy and fault tolerance in modern cloud architectures. However, default scheduling mechanisms primarily optimize for resource availability, often neglecting network topology, inter-node latency, and global resource efficiency, leading to suboptimal task placement in multi-region deployments.

Distributed Kubernetes clusters provide robust solutions for geo-redundancy and fault tolerance in modern cloud architectures. However, default scheduling mechanisms primarily optimize for resource availability, often neglecting network topology, inter-node latency, and global resource efficiency, leading to suboptimal task placement in multi-region deployments. This paper proposes network-aware scheduling plugins that integrate heuristic, metaheuristic, and linear programming methods to optimize resource utilization and inter-zone communication latency for containerized workloads, particularly Apache Spark batch-processing tasks. Unlike the default scheduler, the presented approach incorporates inter-node latency constraints and prioritizes locality-aware scheduling, ensuring efficient pod distribution while minimizing network overhead. The proposed plugins are evaluated using the kube-scheduler-simulator, a tool that replicates Kubernetes scheduling behavior without deploying real workloads. Experiments cover multiple cluster configurations, varying in node count, region count, and inter-region latencies, with performance metrics recorded for scheduler efficiency, inter-zone communication impact, and execution time across different optimization algorithms. The obtained results indicate that network-aware scheduling approaches significantly improve latency-aware placement decisions, achieving lower inter-region communication delays while maintaining resource efficiency.

Priority in task scheduling and resource allocation for cloud computing has attracted significant attention from the research community. However, traditional scheduling algorithms often lack the ability to differentiate between tasks with varying levels of importance. This limitation presents a challenge when cloud servers must handle diverse tasks with distinct priority classes and strict quality of service requirements. To address these challenges in cloud computing environments, particularly within the infrastructure of service models, we propose a novel, self-adaptive, multiclass priority algorithm with VM clustering for resource allocation. This algorithm implements a four-tiered prioritization system to optimize key objectives, including makespan and energy consumption, while simultaneously optimizing resource utilization, degree of imbalance, and waiting time. Additionally, we propose a resource prioritization and load-balancing model based on the clustering technique. The proposed work was validated through multiple simulations using the CloudSim simulator, comparing its performance against well-known task scheduling algorithms. The simulation results and analysis demonstrate that the proposed algorithm effectively optimizes makespan and energy consumption. Specifically, our work achieved percentage improvements ranging from +0.97% to +26.80% in makespan and +3.68% to +49.49% in energy consumption while also improving other performance metrics, including throughput, resource utilization, and load balancing. This novel model demonstrably enhances task scheduling and resource allocation efficiency, particularly in complex scenarios with tight deadlines and multiclass priorities. Full article
