Question

Which among the following statements is false about cross-layer design?

a.

High quality of service can be provided by exchanging information among all layers of the protocol stack

b.

Diverse waveforms are employed for power and modulation process

c.

Cross-layer design helps to eliminate channel variations caused by blurring

d.

Cross-layer design makes channel connections unpredictable

Posted under Cognitive Radio

Answer: (d).Cross-layer design makes channel connections unpredictable Explanation:Cross-layer design creates diverse waveforms to establish predictable connections under the existing channel conditions and medium access control parameters. High quality of service can be provided by exchanging information among all layers of the protocol stack. Cross-layer design also helps to achieve higher throughput.
