(b) Minimize radio presence in the spectrum environment

(c) Maximize radio presence for the networks

(d) Exploit spectrum holes

I had been asked this question in homework.

Question is taken from Next Generation Wireless Network in chapter Next Generation Wireless Network of Cognitive Radio

Answer 1

The correct answer is (d) Exploit spectrum holes

Explanation: The objectives of the cognitive radio are to minimize the radio presence in a network while gathering data about the spectrum from the spectrum environment and to adapt to the available spectrum determined from the gathered data. The dynamic characteristics of the cognitive radio rely on its ability to sense the propagation conditions.
