Introduction Technology has intervened to an extensive degree in the lives of humans. The intervention has made man rely on technology for his business, as well as domestic needs. The trend of transforming regular houses into smart homes has been a field of interest for researchers around the world. Gohn (2007) stated that the advancement in the domain of wireless networking and information technology has made an age-old dream come true of automating one’s house with a centralized source of control. The innovative technology that is responsible for leaping wireless technology to another level of automation is known as Zigbee. The report focuses on the components and network topologies that develop the standard and facilitate communication with devices that are placed within a close range. Section 2 discusses the background and overview of the Zigbee standard. Section 3 includes the components of a Zigbee network while Section 4 discusses the applications of the respective standard. Section 5 includes the network topologies that are followed by the standard and Section 6 defines its placement in the OSI model. 2. Background Several technologies have been developed in the past years that are based on different levels of bandwidth, ranges and degrees of power consumption. Some of the common technologies to provide connectivity with different devices around a smart home have been Bluetooth, Wi-Fi, and WiMax. Leopold, Dydensborg and Bonnet (2003) provided the information that bluetooth is considered to be the first technology in the domain of Wireless Personal Area Network (WPAN) that gained extensive recognition and acceptance. Leopold, Dydensborg and Bonnet (2003) stated that Bluetooth offered omni-directional communication that led to the desire for a smarter technology after some years of its common usage. Stevanovic (2007) provided the information that Zigbee Alliance introduced a new standard with the nam e ‘Zigbee’. Zigbee is a standard which is meant for communication between embedded devices placed in a limited range. It was recognized as a standard under IEEE 802.15.4. Gohn (2007) stated that the main aim behind the standard was to facilitate wireless connectivity between devices such that it would possess the following attributes: Low complexity Low cost Low consumption of power Two-way communication Low load of data transfer Lonn and
