1.	Techniques such as positive acknowledgement and timeouts must be employed to prevent ____ of critical event.(a) delay(b) continuous selection(c) retransmission(d) suspensionI had been asked this question during an online exam.This key question is from Software Architecture Tradeoffs topic in chapter Technology Tradeoffs in Software Defined Radio of Cognitive Radio
Answer» The correct choice is (d) SUSPENSION To explain I would say: Interference generates false messages and masks legitimate messages. The PERMANENT suspension of a FALSELY masked message can be prevented by techniques such as POSITIVE ACKNOWLEDGEMENT and timeout.
