Abstract:
Zigbee is an open technology which was formulated by Zigbee alliance to lead the drawbacks of Bluetooth and Wi-Fi, It is an IEEE 802.15.4 standard developed for wide communications. In this paper we discuss about the Zigbee applications, security, sensors and feature work, about mesh routing and how it works, tree routing and how it works, similarities and difference between mesh and the critical analysis on simulation results
Introduction:
Wireless networking faced a rapid growth in past few decades, at the early invention period this is mainly concentrated on long range and fast communication which is Wi-Fi (IEEE 802.11). Then Bluetooth was originated in 1994 which is mainly focused on low rate WPAN (Wireless Personal Area Network) but a little problem occurs due to its limited range of network (10m). After the deep research in wireless systems IEEE developed a new standard in order to satisfy all the needs like longer battery life, most economical and high security. With these standards IEEE clubbed with Zigbee Alliance to start a new era in the history of wireless networking is ZIGBEE. There are many other wireless networks like Wi-Fi and BLUETOOTH which does not satisfy the complete requirements in control devices and sensors. Though sensors and control devices do not require high bandwidth, they require low energy consumption for long battery life. In order to meet all these requirements ZIGBEE was developed, it allows the battery to last up to years irrespective of changing their cells (Anil 2007). Zigbee supports three types of routing topologies star, mesh and tree. In mesh routing it has connection with all the nodes within the
network. Star routing has hub at the centre at which all other nodes are connected from hub. Tree is also known as hierarchical routing, in this topology the central root node is joined to one or more nodes (Karris 2009).
