Dynamic Optimization Deployment of Wireless Sensor Networks Based on TPWRLS Graph Construction and VFA

With the in-depth research and rapid development of wireless sensor networks (WSNs), dynamic optimization deployment technology has emerged as a research hotspot, aiming to improve the network monitoring effect and reduce the network deployment cost. This paper proposes a novel dynamic optimization deployment strategy for WSNs based on the Two Phase Weighted Regularized Least Square (TPWRLS) graph construction and Virtual Force Algorithm (VFA). Firstly, a mobile node selection strategy based on the TPWRLS graph construction is proposed to select nodes that hold higher values for movement. Secondly, a node movement strategy based on the VFA is proposed to move the selected nodes to appropriate positions, realizing dynamic optimization deployment with the coverage rate as the optimization objective. Simulation results demonstrate that the proposed strategy significantly enhances the coverage rate of WSNs and achieves dynamic optimization deployment of WSNs.
