Extensive energy is consumed by Transceiver communication operation .
Existing research on MAC layer focuses to maximize battery-powered sensor
node's life. Bottleneck of MAC layer protocol design for WBAN is to achieve
high reliability and energy minimization. Majority of MAC protocols designed
for WBANs are based upon TDMA approach. However, a new protocol needs to be
defined to achieve high energy efficiency, fairness and avoid extra energy
consumption due to synchronization.
