The invention relates to a method for determining an optimal transmission path in a data network, wherein the network subscribers (1-14) exchange data in a wireless manner, preferably by radio communication, along a plurality of transmission routes. A first subscriber of the transmission route transmits a search request which can be used as stations of transmission paths by subscribers (1-14) who receive said search request, measure the receiving field intensity, add an identifier to the search request and the measured receiving field intensity, whereupon the search request is subsequently transmitted. The network subscriber (1-14) who is the second subscriber of the transmission route measures the receiving field intensity of the search request and adds to the search request, that which out of all the received search requests contains the optimum transmission route in terms of number of stations and quality of the links between said stations. Said second subscriber of the transmission route transmits said search request thus determined. Each network subscriber (1-14), who receives said search request and whose identifier is contained in said search request stores the identifier registered in the search request prior to his or her identifier as an identifier of a subscriber whose signals are to be retransmitted and retransmits said search request.
