Question

Which among the following is true non-cooperative spectrum sharing?

(a) Non-cooperative spectrum sharing optimizes spectrum sharing algorithms

(b) Non-cooperative spectrum sharing reduces effective spectrum utilization

(c) Non-cooperative spectrum sharing distributes interference measurements to other users in the network

(d) Non-cooperative spectrum sharing works only with spectrum broker

This question was addressed to me by my school principal while I was bunking the class.

Question is from Next Generation Wireless Network topic in portion Next Generation Wireless Network of Cognitive Radio

Answer 1

Correct answer is (b) Non-cooperative spectrum sharing reduces effective spectrum utilization

Explanation: Non-cooperative spectrum sharing only considers the communication of the one particular node. Due to the lack of information about other users, it exhibits reduced spectrum utilization. However due to minimal communication requirements, it is suitable for certain resource-constrained practical applications.
