Zusammenfassung:	The invention discloses a sensor network node positioning method based on wireless transmission delay. The method is used in the wireless sensor network with anchor point and exact time synchronization. By using the method, the position of an unknown node in the wireless sensor network can be accurately measured. The method comprises the following steps: firstly, the unknown node is required to broadcast a positioning message twice; secondly, anchor node captures the positioning message, calculates how long the message reaches the local and uploads the data to a centralized location computing device; and finally the centralized location computing device calculates the position of the unknown node. By adopting the method, the specific position of the unknown node can be calculated effectively, and the invention provides a new way of positioning the node of the wireless sensor network.
