This paper basically compares various wireless networking technologies which can be used for industrial automation and sensing. Among all these technologies, special emphasis is given on Zigbee. Zigbee is a technology known for its low power consumption, low data rates, and self-healing reliable networks, which makes it very efficient for industrial applications. The layer by layer protocol stack architecture of Zigbee illustrates these advantageous features. Zigbee is used for automation and networking purposes in manufacturing and pharmaceutical plants, for monitoring purposes in chemical plants. In this paper, such features and applications of Zigbee are explained with concentration on the networking aspect.

Every robot is connected with numerous sensors which help in automating the whole process. So, once the robot is programmed for a specific task, the sensors then continuously monitor the task being undertaken by the robot and help the robot to perform that task optimally. These sensor values have to be monitored continuously by a system. The system consists of controllers and processors which process the data provided by the sensors and then send control signals to the robots. Now, big manufacturing plants can have hundreds of such robots and taking values of sensors of each robot individually and processing those values is impractical. So, these sensors can all be connected using Zigbee modules and a network can be formed of such sensors. These modules can be then connected in a star or tree topology where each module is connected to the central Coordinator module. The coordinator is connected to a main system where the values of all the sensors are input and processing is done. Then, according to the task of the robot, different control signals can be sent to every …show more content…
FUTURE SCOPE OF ZIGBEE
Zigbee is fast becoming one of the most used wireless networking standard. That is because of its ease of expansion and low power consumption. Zigbee is also used for its interoperability. Nowadays, cellular radiation is one of the problems affecting the lives of people. So, the device used for checking radiation of the base station towers is to be taken near the tower for radiation measurement. Instead of that, if the radiation measuring device is installed with the towers and a Zigbee module is connected to the measuring device, then a network can be created which will send continuous updates to the main system using which radiation can be controlled.
Also, using the gateway device, the Zigbee based devices can be connected to the internet. So, a local or a personal network of an industry can be easily connected to the internet and the data of various such industrial plants can be transferred to a single location for monitoring. The only parameter which has to be considered very carefully is security.
