Patent ID: 8830937

Claim:
A 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, the method comprising: constructing said network making it possible to generate a plurality of active links between at least two active nodes of said network, an active link being composed of two pairs of channels, assigned respectively to transmission and to reception, each comprising a signaling sub-channel and a communication sub-channel, a link being activated according to a degree of relevance, the degree of relevance being determined at least as a function of criteria regarding distance between said nodes and/or of criteria regarding priority between said nodes, each of said active nodes of said network comprising a neighborhood table which groups together the set of active nodes of said network to which it is directly linked by an active link; allocating reception frequency bands to each of said active nodes of said network, said frequency bands being of identical width and spaced apart by a given minimum guard band, said allocating being performed in the following manner: if the number of active nodes of said network is less than or equal to the number of frequency bands available, a different reception frequency band is allocated to each of said nodes; and if the number of active nodes of said network is strictly greater than the number of frequency bands available, a reuse of said frequency bands is effected in such a way that the allocation is performed so as to minimize the interferences between two active nodes which have the same reception frequency band; performing spreading code allocation by each of said receiver active nodes of said network for each of said neighbor transmitter nodes to which it is directly linked by an active link according to an asynchronous CDMA method, said neighbor transmitter nodes communicating with said receiver node in the reception frequency band which has been allocated to it; and performing power control by each of said receiver nodes of said network for each of said neighbor transmitter nodes to which it is directly linked by an active link, said power control step implementing a different power regulation loop for each of said active links emanating from said receiver node having the function of ensuring that all the signals received by said receiver node originating from said transmitter nodes are so with the same power level.
