1.	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 handoffI got this question in an interview for job.The above asked question is from Next Generation Wireless Network in section Next Generation Wireless Network of Cognitive Radio
Answer» Correct ANSWER is (d) Better performance during spectrum handoff The 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.
