Various progressive wireless communication standards were developed and implemented. GSM, Wi-Fi, Zigbee and Bluetooth are well known by most people in the modern society. These standards have penetrated into their daily routine with outstanding popularity. The Wireless Sensor Network (WSN) is built of nodes, from a few to several hundreds or even thousands, where each node is connected to one or sometimes several sensors.
A wireless sensor network (WSN) consists of various distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location. Thus, the Wireless Sensor Network is been proposed for the large range of applications in home, health monitoring and industrial automation. Especially the Zigbee standard that is getting more and more popular in the field of Wireless Sensor Network due to its low data rate and low power consumption. |
