Abstract: Apparatus, and associated method, for dynamically selecting frequencies upon which to define communication channels in a communication system, such as a wireless mesh network. Frequency levels are selected for global use throughout the entire mesh network. And, frequency levels upon which to define local communication channels for individual nodes of the mesh network are also selectable.

Abstract: Apparatus, and an associated method, for providing a mobile node with identifying indicia used to create a care/of address identifying the location of the mobile node. A router advertisement is generated by an access router. The router advertisement includes identifying indicia identifying the identity of the sub-network at which the access router is located. A detector detects the identifying indicia. A broadcast selector selectably broadcasts the identifying indicia to the mobile node. The mobile node utilizes the identifying indicia to form the care/of address.
