Question

Which among the following is not an advantage of employing cross-layer design implementation?

a.

High accuracy of computation results required in algorithms

b.

Elimination of wasteful calculations

c.

High quality of service

d.

Better performance during spectrum handoff

Posted under Cognitive Radio

Answer: (d).Better performance during spectrum handoff Explanation:Cross-layer design improves the accuracy and the productivity of algorithms by extending the amount of information at hand. Cross-layer design helps to adjust in accordance with the varying resource availability. It eliminates computations that are performed due to a lack of communication between the layers of the protocol stack.
