... efficient MAC. A TDMA-based approach has many advantages over other similar techniques such as CSMA/CA and FDMA. Authors of [12] have provided a comparison between TDMA and CSMA/CA as shown in Table ... applications such as BAN. Another argument in favor of using out-of-band wakeup radio is that a wakeup radio-based scheme in BAN can save a significant amount of power. 2.2. Mo...

A quadratic-time approximation makes very few mistakes and remains practically ... 3.
