Abstract: The invention relates to the technical field of a wireless sensor network, and discloses a sensor network node active positioning method based on a smartphone. The method is characterized by comprising the following steps: A, externally connecting a wireless communication module for the smartphone to form a handheld positioner module, wherein the wireless communication module is responsible for carrying out data communication with the smartphone and sensor nodes; B, enabling the handheld positioner module to be close to the sensor nodes; C, collecting position information via the handheld positioner module; D, determining a target node in the sensor nodes; E, transmitting the position information to the target node via the handheld positioner module, so that the target node stores the position information; and F, transmitting node information to the handheld positioner module by the target node, so that the handheld positioner module stores the node information, thereby finishing the positioning. According to the sensor network node active positioning method disclosed by the invention, the best effect in respects of sensor node positioning cost, power consumption, positioning accuracy and the like is achieved.
