【Abstract】 Aiming at the problems of massive information data processing in the micro-grid monitoring system, the transmission of a large amount of data may cause the wireless sensor network to collapse and data loss. An improved DV-hop algorithm based on the microgrid wireless sensor network was proposed. Firstly, edge computing technology was applied to microgrid to improve the structure of microgrid monitoring system. Secondly, on the basis of improving the microgrid monitoring system, the DV hop algorithm based on average weighted method and hop weighted method was organically combined to obtain a new improved algorithm. New algorithm reduces the positioning error of wireless sensor nodes to 0.60. The simulation results show that the average weighted method and hop weighted method improve the positioning accuracy of sensor nodes.更多还原
