Yamin Han et al.

Summary: This study optimizes the deployment of actuators in wireless sensor networks using the hierarchical intermittent communication particle swarm optimization (HICPSO) method, considering the coverage rate of actuators to sensor nodes and the energy consumption rate of sensor nodes as optimization goals to balance energy consumption among sensor nodes and solve energy hole problem. The proposed method effectively increases the coverage rate of actuators to sensor nodes, reduces the energy consumption rate of the sensor nodes, and reduces the packet drop ratio, showing improved performance compared to traditional methods.
