Abstract

The invention provides a node positioning method of a wireless sensor network of a smart power grid. The method comprises following steps of setting multiple fixed nodes as beacon nodes; sending positioning information to multiple surrounding beacon nodes by a mobile node of a wireless sensor network; obtaining the distances between the mobile sensor network node and the multiple fixed nodes through an RSSI algorithm according to the relationship of sending field intensity and corrected receiving field intensity; solving the coordinate information of the mobile sensor network node by using a trilateration method; and correcting the solved coordinate information of the mobile sensor network node by using a maximum likelihood method. According to the node positioning method of the wireless sensor network of the smart power grid provided by the invention, the method is applied to underground power node communication by using a wire and wireless hybrid communication mode, and the node positioning precision in hybrid communication of the heterogeneous network of the smart power grid can be improved.

Description
