JenNet is a protocol stack featuring a rich set
of APIs and ensuring its applications to be interoperable
with ZigBee products from other vendors.
The bottom level comprises IEEE 802.15.4
protocols, a low-cost, low-power solution [3].
Among others, IEEE 802.15.4 MAC is responsible
for message delivery, assembling data frames
to be transmitted, and decomposing received
frames. The IEEE 802.15.4 physical layer is concerned
with exchanging data bits with the wireless
medium and with the layer above.
