An assembly, and an associated method, for an ad hoc network, such as an independent basic service set defined in an IEEE 802.11 protocol specification. A channel map is created and maintained at each mobile station of the ad hoc network. The channel map is populated with channel characteristic indicia of channel frequencies that might be available upon which to be used in the ad hoc network to effectuate communications between the mobile stations. Information related to the channel map created and maintained at each of the mobile stations is exchanged, and any of the mobile stations is selectable to form a DFS owner that defines the channel frequency to be used upon which to define a communication channel for communications in the network.
