a.

Cross-layer intra hub module

b.

Cross-layer interface

c.

Cross-layer scheduler

d.

Cross-layer director

Posted under Cognitive Radio

Answer: (a).Cross-layer intra hub module Explanation:Cross design involves the sharing of information among different layers of the protocol stack. For example, spectrum occupancy information gathered in the physical layer must be accurately transferred to the MAC layer through a proper interface. The units required to implement the cross-layer design are interfaces, controllers, schedulers, and inter hubs.
