Abstract—IEEE 802.15.4 is a current major technology for lowrate
low-power wireless networks. To study the applicability of
IEEE 802.15.4 over a wireless body area network (WBAN), in
this paper we evaluate its three different access schemes’
performance through several metrics. Considering the
coexistence of contention access period (CAP) and contentionfree
period (CFP), we also study the mutual influences of these
two traffics. The results show the unslotted mode has better
performance than the slotted one in terms of throughput and
latency but with the cost of much power consumption. In
addition, the guaranteed time slot (GTS) in CFP can not
guarantee the successful transmission of the CFP frames without
sufficient GTS allocation. Finally, we give the suggestions for the
novel medium access control (MAC) design for a WBAN.
