Question

What is cross-layer design?

a.

Cross-layer design allows non adjacent layers to exchange information which are traditionally relevant to a layer itself

b.

Cross-layer design allows only adjacent layers to exchange information with each other

c.

Cross-layer design provides control of lower layer functions to the upper layer functions

d.

Cross-layer design provides control of upper layer functions to the lower layer functions

Answer: (a).Cross-layer design allows non adjacent layers to exchange information which are traditionally relevant to a layer itself Explanation:Cross-layer design allows non-adjacent layers to exchange information which is traditionally relevant to a layer itself. By adapting cross-layer design, a global view of the radio framework and the surrounding environment can be obtained. It helps to eliminate problems that arise due to a lack of resource information at the time of transmission.
