A method for determining the dynamics of a logical network, said network comprising a plurality of communication nodes (21, 24, 26, i, k). The method comprises obtaining (31), in a node (21) of the network, of at least one item of information (Li, Jk) relating to a modification of the neighborhood of said node, in the course of a predetermined period. The method also comprises determining (33), in said node of the network, of a local dynamics corresponding to at least one sum ( ∑ i ⁢ L ′ ⁢ i , ∑ k ⁢ J ′ ⁢ k ) of at least part of the information obtained.
