Analysis of ZigBee (IEEE 802.15.4 standard) for Star Topology with AODV Protocol

ZigBee is a new wireless technology based on the 802.15.4 standard which is extensively used in wireless communication. This isdesigned for applications like wirelessmonitoring andcontrol of lights, security alarms, motion sensors, thermostats and smoke detectors.ZigBee technology provides a low data rate, low power, and low costwireless networking on the device-level communication.IEEE 802.15.4 specifies physical and media access control layers. The MAC layer defines different network topologies, namely a star, tree and mesh topology. In this paper, we give a brief overview of ZigBee (IEEE 802.14.5 standard) which is the fundamental of low ratewireless personal area network (LR-WPAN).Then we analysis the performance of ZigBee (IEEE 802.15.4) for star topology with different traffic scenarios namely CBR, FTP, and Poissonusing thesimulation tool NS-2.
