Suppose that all sensor nodes are in normal situation till the [k.sup.th] superframe where the emergency condition occurs.
In beacon enabled mode, coordinator starts the superframe that consists of a beacon, an active period, and an inactive period, as shown in Fig.
Section 3 describes basic assumptions and a superframe structure.
Also, PAN has a superframe structure which consists of active part and inactive part.
After calculating the optimal [CW.sub.max], the AP broadcasts the beacon frame, including the optimal [CW.sub.max], at the start time of the superframe. Then, all stations receiving the beacon frame use this information to set their maximum contention window size to the optimal value.
[6], an ISA100.11a system was studied, where the effects of the time slot duration, superframe period, and back-off exponent on various packet-level measures such as throughput, average delay, and energy consumption were evaluated.
When people are not on a call, Portal's "Superframe" can display favourite photos and videos and important notifications like birthday reminders .
Portal also has a feature called Superframe, that can display a user's photos, videos and notifications like birthday reminders on the display.
This is due to limited 16 channels in IEEE 802.15.4 MAC, which is not feasible for N heterogeneous nature of a patient's data.The limitations in CSMA/CA reduces performance of the MAC Superframe structure in terms of a higher data collision.
The IEEE 802.15.4 standard superframe layout has the inactive span and an active span.
The protocol in cluster-tree mode uses superframe structure (Figure 2), where a TDMA-based period is used for guaranteed access, while a contention-based period is used for nonguaranteed access.
