1.	Which among the following is false about the routing issue link failure?(a) Interference is a route metric used to represent link failure(b) Link capacity is a route metric used to represent link failure(c) Link failure is caused by the displacement of an intermediary node(d) Link failure is caused by the arrival of the primary userThe question was posed to me by my college professor while I was bunking the class.This question is from Next Generation Wireless Network topic in division Next Generation Wireless Network of Cognitive Radio
Answer» The correct choice is (b) Link capacity is a route metric used to represent link failure Explanation: Link failure arises due to the ARRIVAL of a primary USER or due to the LACK of replacement of a DISPLACED intermediary node. Link failure, depending on the triggering event, may be RECOVERED by employing an extra power signal.
