The wireless sensor network is a crucial component of the Internet of Things (IoT), and ensuring its efficient operation has become one of the prominent research challenges today. By incorporating energy-replenishable heterogeneous nodes into the network, it is possible to effectively extend the network's lifespan. This paper establishes criteria for selecting the locations of heterogeneous nodes based on characteristics such as network coverage and data transmission distance. We propose an optimization deployment algorithm specifically designed for positioning heterogeneous nodes within heterogeneous wireless sensor networks, and we conduct a simulation analysis comparing our proposed algorithm with existing methods. The results indicate that our proposed algorithm demonstrates superior performance in terms of data transmission volume and energy consumption.
