Wireless Sensor Networks A wireless sensor network consists of distributed sensors to monitor physical environmental conditions. These include factors like temperature, humidity, light etc. They monitor such parameters and then pass the data via the wireless network to the main location. There are also sensors available that can work bi-directional enabling control of sensor activity. Such kind of wireless sensors were inspired by the military applications, like those implemented on the battlefield for surveillance. Now-a-days similar sensor networks are utilized for many industrial and consumer applications, like machine health monitoring, industrial process monitoring and control and even by private home owners too. The wireless sensor network is made of nodes. These can range from several hundred to thousands of nodes. Each node is usually connected toone sensor. Thus each sensor node of the network has several different parts like a radio transceiver with an in...
