Industrial Centric Node Localization and Pollution Prediction Using Hybrid Swarm Techniques

Abstract

Major fields such as military applications, medical fields, weather forecasting, and environmental applications use wireless sensor networks for major computing processes. Sensors play a vital role in emerging technologies of the 20th century. Localization of sensors in needed locations is a very serious problem. The environment is home to every living being in the world. The growth of industries after the industrial revolution increased pollution across the environment. Owing to recent uncontrolled growth and development, sensors to measure pollution levels across industries and surroundings are needed. An interesting and challenging task is choosing the place to fit the sensors. Many meta-heuristic techniques have been introduced in node localization. Swarm intelligent algorithms have proven their efficiency in many studies on localization problems. In this article, we introduce an industrial-centric approach to solve the problem of node localization in the sensor network. First, our work aims at selecting industrial areas in the sensed location. We use random forest regression methodology to select the polluted area. Then, the elephant herding algorithm is used in sensor node localization. These two algorithms are combined to produce the best standard result in localizing the sensor nodes. To check the proposed performance, experiments are conducted with data from the KDD Cup 2018, which contain the name of 35 stations with concentrations of air pollutants such as PM, SO 2 , CO, NO 2 , and O 3 . These data are normalized and tested with algorithms. The results are comparatively analyzed with other swarm intelligence algorithms such as the elephant herding algorithm, particle swarm optimization, and machine learning algorithms such as decision tree regression and multi-layer perceptron. Results can indicate our proposed algorithm can suggest more meaningful locations for localizing the sensors in the topology. Our proposed method achieves a lower root mean square value with 0.06 to 0.08 for localizing with Stations 1 to 5.

Plastic Industry Development and Natural Environment Protection

“…c i 0 is a defined value, expressed as the minimum concentration of microplastics at all sampling points. PLI refers to the load index of micro plastics and is used as the ecological risk assessment index of micro plastics [12,13].…”

The Early Warning Model of Sudden Water Pollution Based on the Latent Factor

“…The latter class is divided into supervised, semi-supervised and unsupervised learning based on the dataset labels. Supervised is a way to label normal and abnormal water quality, semi-supervised only labels normal water quality conditions, and unsupervised learning does not label all data [7]. According to the actual situation, water quality anomalies are more difficult to make labeling, so unsupervised and semi-supervised are more commonly used in water quality anomaly detection.…”

Water Pollution Prevention and Prediction Based on Grey BP Neural Network Model

“…Continue to improve the construction of a high standard network in core areas to achieve a step change in the construction of wastewater treatment systems. Assess coordinated improvements in sewerage planning and construction stations in areas where there is a serious lack of sewerage capacity and accelerate the renovation of wastewater treatment plants [17]. Accelerate the dredging, testing and rehabilitation of the sewerage network and complete the rehabilitation of the sewerage network such as fault excavation and repair in a timely manner.…”
