Introduction of ZigBee

ZigBee is a standard for a suite of high level communication protocols using
small, low-power digital radios based on the IEEE 802.15.4-2003 standar d for
wireless personal area networks (WPANs). The technology defined by the
ZigBee specification is intended to be simpler and less expensive than other
WPANs, such as Bluetooth. ZigBee is targeted at radio-frequency (RF)
applications that require a low data rate, long battery life, and secure
networking.

ZigBee protocols are intended for use in embedded applications requiring low
data rates and low power consumption. ZigBee's current focus is to define a
general-purpose, inexpensive, self-organizing mesh network that can be used
for industrial control, embedded sensing, medical data collection, smoke and
intruder warning, building automation, home automation, etc.

ZigBee is a mesh network architecture (see Picture 1). Its network layer
supports three types of topologies: both star and tree typical networks and
generic mesh networks. As one of its defining features, ZigBee provides
facilities for carrying out secure communications, protecting establishment and
transport of cryptographic keys, cyphering frames and controlling devices. It
builds on the basic security framework defined in IEEE 802.15.4.
