Question

Which among the following is a concern of a primary user?

a.

Link maintenance probability

b.

Number of handoff

c.

Handoff latency

d.

Effective data rate

Posted under Cognitive Radio

Answer: (c).Handoff latency Explanation:Spectrum handoff is the process of transferring current data communication from one channel to another channel. The delay caused by spectrum handoff is termed as handoff latency. High handoff latency at the secondary user increases the amount of interference at the primary user.
