Damping-Assisted Evolutionary Swarm Intelligence for Industrial IoT Task Scheduling in Cloud Computing

Abstract

In recent years, ongoing advancements in the Industrial Internet of Things (IIoT) have yielded massive volumes of data, taxing the capabilities of cloud computing infrastructure. Allocating limited computing resources to numerous incoming requests is one of the difficulties of cloud computing, which is typically referred to as a Task-Scheduling-in-Cloud-Computing (TSCC) problem. In order to ameliorate the performance of a particle swarm optimizer (PSO) and broaden its application to TSCC, this paper introduces an Opposition-based Simulated Annealing Particle Swarm Optimizer (OSAPSO) to address PSO's premature convergence issue, particularly when tackling high-dimensional complex problems like TSCC. OSAPSO is a novel combination of opposition-based learning (OBL), evolution strategy, simulated annealing (SA), and swarm intelligence. At its initial stage, the swarm is formed at random by using OBL to guarantee swarm diversity with a light computational burden. A multi-way tournament selection approach is then utilized to pick parents to produce a new offspring swarm by using two novel evolutionary operators, namely, damping-based mutation and inversion-scrambling-based crossover. OSAPSO is given a powerful exploration capacity by adopting the survivor probabilistic selection of SA, which accepts subpar solutions with a certain probability. Finally, PSO itself kicks in, making a good trade-off between solution diversity and convergence speed of the proposed method. Due to the non-convex discontinuous nature of TSCC, OSAPSO is modified to clone it into a discrete optimization problem. Within a heterogeneous cloud computing environment, OSAPSO and eight well-regarded competitors are examined on a set of multi-scale IIoT heterogeneous task groups (realistic and synthetic). In terms of power consumption, monetary cost, service makespan, and system throughput, experimental results reveal that OSAPSO has a winning performance and is statistically more This paragraph of the first footnote will contain the date on which you submitted your paper for review.

Cluster Based Improved Particle Swarm Optimization for Optimum Cluster Head Election for Energy Efficient Routing in Wireless Sensor Networks

“…The specific calculation method for updating the velocity components and positions is defined based on the relationships between these parameters and is further elaborated in reference [15]. This method guides the iterative adjustments in the positions of candidate cluster head nodes, ultimately leading to optimization results in the Wireless Sensor Network (WSN).…”

“…These updates are influenced by factors such as the inertia weight (w), indicating the impact of the previous round's velocity, cognitive learning factor (c1) and social learning factor (c2), representing acceleration based on proximity to local and global optimal positions, and random numbers (r1 and r2) for introducing variability. The specific calculation method for updating position components is described in reference [15] and guides the iterative adjustments, ultimately optimizing the positions of candidate cluster head nodes in the Wireless Sensor Network (WSN).…”

“…This makes the algorithm easy to understand, implement and apply [24]. At present, it has been applied to the stochastic disassembly line balancing problems [25], scheduling problems [26,27], knapsack problems [28], system identification problems [29] and quadratic assignment problems [30]. In this work, we choose to use MBO to solve DLBP with tool deterioration.…”

Secured Dynamic Request Scheduling and Optimal CSP Selection for Analyzing Cloud Service Performance Using Intelligent Approaches

“…To address growing concerns about cloud security and privacy, the security-on-demand service mode dynamically provides cloud users with trusted computing environments in response to their specific security requests. Designing suitable authentication and authorization solutions is one of the most important components of confidentiality and safety concerns in limited resources IoT gadgets [5]. An efficient method for predicting privacy breaches in cloud environments can be found in the design of cloud forensics based on blockchains.…”
