As already alluded to in previous chapters of this book, ZigBee is arguably the most promi-

nent alliance dedicated to low-power embedded systems. It is a facilitator of applications

pertaining to home and building automation, smart metering, health care, among many

others. Its link and access protocols rely on the speciˉcations of IEEE 802.15.4 [1], whereas

higher layers are subject to the proˉle deˉnition of the ZigBee special interest group (SIG).

The internet engineering task force (IETF), however, has lately commenced standardizing

networking protocols within their 6LoWPAN [2] and ROLL [3] which are assuming IEEE

802.15.4 link layer technology ZigBee may thus adopt IETFs networking solution in the

future. In short, ZigBee is gaining in importance and the underlying IEEE standard ensures

that technology is available multiple vendors.-As already alluded to in previous chapters of this book, ZigBee is arguably the most promi-
