28. doc.: IEEE 802.15-07-0972-00-0005 Submission November 2007 Suk-Hyun Song (NIA), and Ho-In Jeon (KWU) Slide 28 Conclusions WiBEEM protocol has unique features of supporting low power consumption, device mobility, and QoS. There are many examples of services that require device mobility and QoS. –Facility management –Healthcare Services –Disaster Prevention Enhancement of IEEE 802.15.4 MAC has to be made that can support QoS and device mobility over mesh network. WiBEEM protocol is one of the possible candidates.
