For past few years, there is a rapid advancement in the wireless network area. These are compact sensors with narrow power and finite resources. However, there are numerous variants of wireless technologies, such as Wireless HART, IEEE 802.15.4, Wibree, IETF 6LoWPAN, ISA100.11, IEEE 802.15.3, Wimax, and ZigBee. Among these wireless standards, a latest standard called ZigBee is invented in the past few years. ZigBee is a wireless standard used for Control and sensor networks. It is based on the IEEE 802.15.4 standard. Zigbee is designed for low-power consumption compensating batteries to last longer. The low cost technology allows it to be deployed in wireless control and monitoring application, where longer life with smaller batteries equipment is needed. Zigbee has mesh networking which provides high reliability and larger range. ZigBee is designed to meet the growing demand of wireless networking. This paper provides a review on ZigBee technology and includes ZigBee Alliance, characteristics of ZigBee, ZigBee Protocol stack, access method, topologies, applications, and advantages of ZigBee.
