Abstract

Using bearer channels for wireless nodes includes initiating communication among the wireless nodes that include a node and one or more neighbor nodes. An adaptive channel operable to communicate messages between the node and the neighbor nodes is established. One or more bearer channels are selected. The one or more neighbor nodes are notified of the one or more selected bearer channels using the adaptive channel. The node and the neighbor nodes communicate over the bearer channels.
