The Era of Wireless Sensor Networks

The Era of Wireless Sensor Networks: Automation has made us see many unknown and unexpected things, which were once only a mere imagination. Throughout the ages, hard work and unique thought processes have resulted in the possibility and existence of such innovations. For example, once a upon a time, one could only think about a circuit full of wires, but the gradual modification has resulted in such a smooth technology in which there is minimal application of wires and it is a fact that one cannot question the capability of the wireless system.

The concept of sensors was a big discovery in itself as there are multiple ways through which this particular device can be utilized for useful purposes. There are a large number of sensors which are used nowadays such as temperature sensors, pressure sensors, fingerprint sensors and much more. Scientists have employed all their potential in order to extract the majority of services from these sensors and depending upon the needs of the field of technology, several new sensors are emerging every day.

How does Wireless Sensors work?

Wireless sensors are a combination of small, self-directed sensor nodes or motes which are used to fetch important data from fields of interest. This is a fact that a combination of wireless sensors are used to fetch the data as the area under observation is quite large. According to resources, the systems of wireless networks are designed in the following format so that the information is properly extracted and processed to be analyzed:

  1. Physical Layer
  2. Data Link Layer
  3. Network Layer
  4. Transport Layer
  5. Application Layer

The wireless sensors are devised in such a way which can facilitate every need of the regulator and controller. These products are developed in this way to ensure that they consume limited power and can also endure the adverse climatic conditions. If we consider the aspect of probable failures in the sensor nodes, that aspect is also checked before the initiation, however, in cases of emergency, it can be treated as well. Due to these additional benefits, one can also use wireless sensors in remote locations. Apart from this, these systems possess the capability to accommodate another miniature system if there is a particular requirement from the central administration system.

The most important fact is that these products and their execution are comparatively cheaper, so they can be conveniently used in several fields such as air pollution monitoring, detection of a forest fire, detection of landslides, or other abnormalities in the environment.
