IEEE/ICACT20260317 Question.6 Questioner: tanghr@dsp.ac.cn 2026-02-07 오전 10:27:06	IEEE/ICACT20260317 Answer.6 Answer by Auhor pangb@dsp.ac.cn 2026-02-07 오전 10:27:06
Why can FRAB-MAC significantly reduce the number of silent nodes? What is the direct relationship between this reduction and the reliability factor Rs?	FRAB-MAC estimates the packet success rate between nodes and explicitly considers link reliability. Instead of arbitrarily selecting the next transmitting node, it arranges nodes with higher recovery success probability into the transmission sequence, ensuring reliable communication between consecutive nodes. As a result, nodes can either directly receive or successfully recover control packets, and a higher reliability factor leads to fewer silent nodes.
