The invention relates to a method of creation of a new communication network by a wireless terminal. The wireless terminal is initially part of an existing centralized network that includes an access point able to control the association of wireless terminals to its network. In the event of disassociation of the terminal from the network, the method makes provision to initiate a procedure for creating a new network including a declaration of the terminal as access point of the new network, where the operating parameters of the new network are such that communications on the new network do not interfere with the existing network.
