QoS-based energy-efficient protocols for wireless sensor network

Abstract

Clustering routing protocols for WSNs have evolved. Indeed, the protocols combine several sensor nodes, and the resultant clusters translate into hierarchical management systems, having integrated the features of different cluster members to the base stations and cluster heads. This study seeks to extend the literature and ensure efficient actions by proposing QoS-based energy-efficient protocols for WSNs, which provide QoS via energy consumption and end-to-end delay. The motivation of the study is to develop a protocol architecture that could extend network lifetimes, balance and reduce the energy consumption of networks, reduce redundancy, and increase information validity and integrity. The MATLAB software is used to perform the simulations. Through multiple time simulations, some of the performance metrics that are analyzed include the percentage of dead nodes, the average energy consumption for each node, the throughput, delay, network lifetime, fraction of alive nodes, and the optimum quantity of CHs in different rounds. Compared to the previous network protocols, it is also evident that the proposed model maintains stability relative to the determination of cluster head optimal values in the respective rounds. Similarly, the protocol outperforms frameworks such as ATEER, EDDEEC, and DEEC relative to the parameters of network throughput and delay, energy efficiency, and network lifetime, proving superior.
