Question

Which among the following is not a challenge of employing reasoning and learning stage in the cognitive radio?

(a) Computational requirement

(b) Quality of Service

(c) Edge conditions

(d) Predictable behaviour

This question was posed to me in quiz.

My doubt stems from Next Generation Wireless Network topic in division Next Generation Wireless Network of Cognitive Radio

Answer 1

Correct choice is (b) Quality of Service

To explain: Cognitive radio should provide a large amount of computational resources to achieve the results of each operation. Edge conditions refer to the devices which are positioned in a location without regular service and hence cannot benefit from learning techniques. Predictable behaviour refers to the ability to estimate the outcome of each step of the operation but not the final outcome.
