Question

Which among the following is integrated in IEEE 802.22 Wireless Regional Area Network?

a.

Route decision model

b.

Back up channel list

c.

Interference floor

d.

Spectrum decision model

Posted under Cognitive Radio

Answer: (b).Back up channel list Explanation:The most preferred approach for mitigating performance degradation, due to poor channel characteristics, is building a backup channel list. The potential target channels are added to a list. The list is maintained by sharing information between users in the area. It is integrated in the IEEE 802.22 Wireless Regional Area Network.
