Toxic gas leakage that leads to equipment damage, environmental effects, and injuries humans is the key concern in large-scale industries, particularly petrochemical plants. Industrial wireless sensor networks (IWSNs) are specially designed for industrial applications with improved efficiency, remote sensing toxic leakage. Sleep scheduling a common approach IWSNs overcome network lifetime problem due energy constrained nodes. In this article, we propose sleep scheme ensures coverage degree requirement based on dangerous levels of area, while maintaining global connectivity minimal awake Unlike previous algorithm, example, connected k-neighborhood (CKN)-based wakes up nodes over entire field by increasing k-value, our proposed dynamically only particular area. Simulation results show outperforms CKN-based same required addition, considers multiple hazardous zones various requirements. We at expense slight extra message overhead, consumption terms totally reduced compared other approaches, connectivity.
