Wireless Sensor Network Using Ns3

WSN expanded as Wireless Sensor Network is a cluster of open freely dispersed and out-and-out sensors that performs the task of monitoring and recording all the ongoing environmental conditions of a data, such as temperature, humidity, pollution levels and many other important factors. Additionally they also systematize the collected data to a fundamental location hub. The wireless sensor network depend mostly on rapid development of networks and wireless connectivity, this makes it similar to wireless ad hoc networks.

WSN does so in order to transfer sensor data wirelessly. Wireless sensor network is also known by another name, dust networks as the minuscule sensors are as diminutive as dust. They perform all their tasks automatically. The major motive for creating wireless sensor network is its application in a range of military devices namely battlefield surveillance. It also benefits various other fields such as industrial and consumer applications. In industries it helps monitor industrial process and health status of machine. Wireless sensor networks are made up of thousands of nodes. It is created by connecting one node to another or to several at the same time.

A sensor node is a composition of multiple parts namely, an internal antenna and external antenna, a battery with energy harvesting, a microcontroller, a radio transceiver and an electronic circuit to line up sensors. The size of the sensor node differs from that of a cardboard box to small grains of dust as well as the cost varies depending on the compound nature of the individual nodes. A restriction on communication bandwidth, its memory and speed is caused by the limitation in the size and cost of nodes. Routing or flooding is the two propagation technique among the network hops. Apart from this wireless sensor networks also act as a vigorous research area in the fields of telecommunications, information technology and computer science. This is accomplished with the help of the latest version of network simulator, NS3 a discrete event network simulator.
