Shrnutí:This work presents a utility-based adaptive sensor placement and reconfiguration (UASPAR) approach designed to optimize sensor node (SN) allocation and dynamic reconfiguration for energy-efficient wireless sensor networks (WSNs). UASPAR employs a utility-driven strategy to assign SNs to specific regions, aiming to achieve optimal coverage while maintaining network balance. The proposed utility function incorporates key parameters such as residual energy, proximity to the base station (BS), and energy offset, defined as the deviation of an SN's energy level from the network's average energy. The WSN is structured using concentric circular annular regions, with each region initialized with predefined utility thresholds and capacity constraints. SNs surpassing these thresholds and meeting the constraints are strategically placed to minimize node failures and prevent inactive network zones. This adaptive mechanism ensures energy-aware placement and maintains network longevity. Extensive simulations validate the effectiveness of UASPAR in comparison with existing state-of-the-art techniques. Results indicate that UASPAR reduces node mortality by over 30%, decreases energy depletion by more than 35%, and improves throughput and data transmission efficiency by over 25%. These improvements collectively contribute to enhanced energy management, prolonged network lifetime, and superior overall performance, making UASPAR a promising solution for sustainable WSN deployment.
