Method for multiple access to the radio resources in a mobile ad hoc network comprising a plurality of communicating mobile terminals or nodes, having known geographical coordinates, including constructing the said network, allocating reception frequency bands to each of the said active nodes of the said network, the said frequency bands being of identical width and spaced apart by a given minimum guard band, spreading code allocation performed by each of the said receiver active nodes of the said network for each of the said neighbor transmitter nodes to which it is directly linked by an active link according to an asynchronous CDMA method, and power control performed by each of the said receiver nodes of the said network for each of the said neighbor transmitter nodes to which it is directly linked by an active link.
