Wireless sensor network is a new type of information perception, collection and processing technology used by humans to study the physical world. In this paper, combined with the current mainstream positioning algorithms of wireless sensor network nodes, a ubiquitous IoT positioning algorithm for power systems is proposed. The technical research method combining mathematical models, using the linearization method of coordinate system translation, that is, a new method to eliminate the nonlinear variables of the observation equation through the corresponding formula transformation, thereby reducing the amount of calculation (low power consumption) and achieving better positioning performance , A localization algorithm that meets the needs of various scenarios is the ultimate research goal..
