A node in a wireless communication system detects a requirement to discontinue communications on a primary channel. In response, the node sends a message to a plurality of nodes, which includes a reason for discontinuation of communications on the primary channel and availability of immediate operation of a secondary channel. The secondary channel is a channel the node was currently using for its communication. Another node receives a message including a requirement to discontinue communications on a primary channel and also the availability of immediate operation on a secondary channel. The receiving node detects the feasibility of moving the operation of its associated network to the secondary channel. When feasible, the node sends a message to other nodes to make the secondary channel its primary channel.
