The present invention relates to a method for establishing a sensor network having multiple sensor nodes, sensor nodes being able to connect to one another to transmit sensor data to a central receiving node, and information, in particular time information, being in stored in every sensor node from other neighboring sensor nodes lying in the reception area of a sensor node, on the basis of which a sensor node determines when to connect to another sensor node, initial information in the sensor node (S2) being formed by information from a mobile installation device (MGW), which is transmitted into a new sensor node (S2) during the installation thereof, the information particularly being provided in the form of a table.
