Abstract: Abstract The fact that sensor nodes are situated in specific places is most obvious in wireless sensor networks. A wireless sensor network has been designed to address node localization through several solutions. Environmental monitoring, healthcare, and industrial automation are just some of the fields where wireless sensor networks (WSNs) find extensive application. This sort of WSN application is fundamentally dependent on the accurate localization of sensor nodes. The purpose of this paper is to propose an enhanced received signal strength indicator (RSSI) technique for determining unlocalized nodes using anchor nodes. An optimal communication range, aligning with the application needs, can be determined by assessing the dynamic correlation between communication distance and the RSSI throughout the localization procedure. The advanced RSSI-based node localization method proposed in this study involves two distinct stages: the distance determination phase and the computation phase. In this work, we assess the outcome using the Castalia simulation. The precision of wireless sensor network node location is greatly improved by integrating mobile anchor nodes with RSSI-based dynamic node localization. The results of the simulations and the subsequent analysis attest to the excellent accuracy and low energy consumption of the suggested method during the localization procedure.
