GWO‐C: Grey wolf optimizer‐based clustering scheme for WSNs

International Journal of Communication Systems, 2020
SummaryA wireless sensor network (WSN) is a prominent technology that could assist in the fourth industrial revolution. Sensor nodes present in the WSNs are functioned by a battery. It is impossible to recharge or replace the battery, hence energy is the most important resource of WSNs.

Grey wolf optimizer and hybrid PSO‐GWO for reliability optimization and redundancy allocation problem

Quality and Reliability Engineering International, 2023
AbstractAnalysis and optimization of system reliability have very much importance for developing an optimal design for the system while using the available resources. Several studies are centered towards reliability optimization using metaheuristics. In this study, a recently developed metaheuristic optimization algorithm called hybrid PSO‐GWO (HPSGWO)

I-GWO and Ex-GWO: improved algorithms of the Grey Wolf Optimizer to solve global optimization problems

Engineering with Computers, 2019
In this paper, two novel meta-heuristic algorithms are introduced to solve global optimization problems inspired by the Grey Wolf Optimizer (GWO) algorithm. In the GWO algorithm, wolves are likely to be located in regions close to each other. Therefore, as they catch the hunt (approaching the solution), they may create an intensity in the same or ...

Grey Wolf Optimization (GWO) Algorithm

2017
This chapter describes the grey wolf optimization (GWO) algorithm as one of the new meta-heuristic algorithms. First, a brief literature review is presented and then the natural process of the GWO algorithm is described. Also, the optimization process and a pseudo code of the GWO algorithm are presented in this chapter.

TS-GWO: IoT Tasks Scheduling in Cloud Computing Using Grey Wolf Optimizer

2020
The most critical action in the Internet of things (IoT), particularly in the cloud computing (CC) ecosystem, is job/task scheduling. The rule of the task scheduling (TS) means that how to arrange/schedule the jobs over the given virtual machines (VMs) by decreasing the Makespan measured (Mm) values and the cost need.

Solving Optimal Coordination of Direction Overcurrent Relays Problem Using Grey Wolf Optimization (GWO) Algorithm

2018 Twentieth International Middle East Power Systems Conference (MEPCON), 2018
The optimal coordination of DOCRs becomes a very hard task as the power system becomes complex and larger. In this paper, the recent GWO technique is proposed to find the optimal settings for directional overcurrent relays (DOCR), minimize the total operation time for all primary relays, and maintain the relay coordination margin between relay pairs ...
