Medium Access Control (MAC) protocols play a significant role in maximizing the lifetime of Wireless Body Area Network (WBAN) by controlling the dominant sources of energy waste, i.e., collision, idle listening, overhearing, and control packet overhead. Considerable research efforts are devoted to develop an energy efficient MAC protocol for WBAN. For this purpose, researchers have conducted a comprehensive study of the well-know low-power MAC protocols including WiseMAC, SMAC, IEEE 802.15.4 and PB-TDMA, and concluded that none of these protocols accommodate the heterogeneous traffic requirements of WBAN. Most of them were unable to satisfy the stringent Quality of Service (QoS) requirements.
