Abstract:
IEEE 802.15.4 is the standard for data communications with business and consumer devices
which is designed around low-power consumption allowing batteries to essentially last forever.
The ZigBee standard provides network, security and application support services operation on
top of the IEEE 802.15.4 Medium Access Control (MAC) and Physical Layer (PHY) wireless
standard. It employs a suite of technologies to enable scalable, self-organizing, self-healing
networks standard. The low cost allows the technology to be widely deployed in wireless control
and monitoring applications, the low power-usage allows longer life with smaller batteries and
the mesh networking provides high reliability and larger range. ZigBee has been developed to
meet the growing demand for capable wireless networking between numerous low-power
devices. This paper provides a brief description of the newly introduced ZigBee standards. It
focus on developing Network Simulator (NS2) models for the ZigBee protocol and the
performance evaluation of these models. Several simulations were run and the results were
analyzed for the different scenario.
