Based on the existing wireless sensor network DV-Hop algorithm and its improvement ideas, inheriting the advantages of various thinking algorithms, and combining with the low energy consumption requirements of wireless sensor networks, this paper proposes an energy-saving and high-precision DV-Hop positioning method, and the corresponding simulation experiment has be carried out. The experimental results show that under the experimental scenario, when the proportion of anchor nodes is 10%, the

In the case of different anchor node ratios and network connectivity at 10, the number of flooding packets can still be reduced by more than 10%. Therefore, the improved DV-Hop algorithm has better energy efficiency than the classical DV-Hop algorithm, achieving the purpose of energy saving.
