Wireless communication technology is one of the key technologies for the construction of the energy Internet,however,the existing wireless network has problems such as load network imbalance,poor stability,and difficult maintenance.For these reasons,this paper proposes a clustering wireless self-optimizing dynamic networking method.This method designs three link dynamic factors,including network quality,relay level and network capacity,which can be applied not only to the smart electricity meter acquisition system powered by the mains,but also to the battery powered meter acquisition system.In order to solve the low power consumption problem of the battery powered system,the battery level dynamic factor is further introduced,which solves the key technologies,such as flexible networking and automatic optimization of data communication path to form the best cluster.Meanwhile,through the establishment of a typical field application LoRa wireless network environment,it has effectively verified the influence of various link dynamic factors on the success rate and stability of wireless network communication.After using these wireless self-optimizing link dynamic factors,the optimal network path and load balancing effect can be obtained automatically.
