What are wireless sensor networks?

In computer networking there is a great value of wireless networking because it has no difficult installation, no more expenditure and has lot of way to save money band time. In the field of wireless networking there is another form of networking which is called as wireless sensor network. A type of wireless networking which is comprised on number of numerous sensors and they are interlinked or connected with each other for performing the same function collectively or cooperatively for the sake of checking and balancing the environmental factors. This type of networking is called as Wireless sensor networking. Basically wireless sensor networking is used for monitoring the physical conditions such as weather conditions, regularity of temperature, different kinds of vibrations and also deals in the field of technology related to sound.
Some times it is also used in pressure, and also checking the environmental pollutants. These sensors which are used collectively for performing a function are distributed spatially other wise it is difficult for the sensors to perform cooperatively to play a role in monitoring. Scientists develop wireless sensor networking on the bases of inspiration from the application known as battle field surveillance which is completely a military application. As we know that this technology has great importance in the field of computational world and where it has computational importance it also has importance in industry. It is also play an important part in civilian technologies like monitoring of traffic control and many others.


How wireless sensor network works?


Total working of wireless sensor networking is based on its construction. Sensor network initially consists of small or large nodes called as sensor nodes. These nodes are varying in size and totally depend on the size because different sizes of sensor nodes work efficiently in different fields. Wireless sensor networking have such sensor nodes which are specially designed in such a typical way that they have a microcontroller which controls the monitoring, a radio transceiver for generating radio waves, different type of wireless communicating devices and also equipped with an energy source such as battery. The entire network worked simultaneously by using different dimensions of sensors and worked on the phenomenon of multi routing algorithm which is also termed as wireless ad hoc networking.


Applications of Wireless Sensor Networking:


In the present era there are lot of technologies which are used for monitoring are completely based on the wireless sensor networking. Some of important applications are environmental monitoring, traffic control application, weather checking, regularity checking of temperature etc. Wireless sensor networks can also be used for detecting the presence of vehicles such as motor cycles up to trains. These are some important wireless sensor networking based technologies which help us in our daily life. Some of there daily life applications are: used in agriculture, water level monitoring, green house monitoring, landfill monitoring etc.


Pros and Cons of Wireless Sensor Networking:


There are many advantages of wireless sensor networking some of important prose’s are: they can store a limited source of energy, they have no hassle of cables and has mobility, one of its major advantage is that it can work efficiently under the harsh conditions, and it has deployment up to large scale etc. Where it has advantages at the same time it also has some disadvantages which really take the moral of this technology down such as they have very insufficient speed of communication, it is to disturb the propagation of waves and hack your networking and the major disadvantage of wireless sensor networking is it is too costly to use.


Future of wireless sensor networks:


But wireless sensor networking has a bright future in the field of computer networking because we can solve the monitoring problems at an advanced level in the future with the help of such technology of networking.
