ZigBee is arguably the most prominent alliance dedicated to low-power embedded system. Its PHY and MAC layer protocols rely on the specification of IEEE 802.15.4. In this paper, we briefly detail the IEEE 802.15.4 MAC layer protocol, especially the slotted CSMA/CA algorithm. Then we calculated the average transmission delay. At last, we proposed an improved algorithm of the average transmission delay time, compared the result with the original algorithm and illustrated the simulation's application scenarios.
