What is a Wireless Sensor Network (WSN)?
Wireless Sensor Network (WSN) is a simple wireless-based network that doesn’t require infrastructure and it is applied in several wireless-based sensory devices with an ad-hoc type of network configuration. The primary roles of these WSNs are as follows:
It is utilized to track any activities in a considered system.
It is utilized to track any physical parameters by integrating with many hardware.
It is utilized to track any kind of factors like pressure, temperature, etc in our environment.
What are the Types of Wireless Sensor Networks?
The most common types of WSNs are given below.
Underwater WSNs
Mobile WSNs
Terrestrial WSNs
Underground WSNs
Multimedia WSNs
Underwater WSNs
Water is the earth's resource that occupies over seventy per cent of space. This type of Underwater WSNs will be deployed in underwater conditions with several autosomal vehicles and sensor nodes. These autosomal vehicles will be utilized to gather data from the deployed sensory devices in underwater conditions. The sensors deployed will usually be less power restricted battery which doesn’t allow for the recharge or replacement.
Mobile WSNs
As the name suggests, these Mobile WSNs are always mobile (i.e.) it is designed to move on its own in order to manipulate, communicate, and sense various data that got gathered from the deployed sensor nodes. As these types of WSNs offer mobility for data gathering, it is able to cover a vast amount of area than the conventional non-moving WSNs along with the improvisation in terms of energy.
Terrestrial WSNs
As the name suggests, these Terrestrial WSNs are always deployed in terrestrial lands. These Terrestrial WSNs are utilized for communications taking place in various base stations for efficient data gathering. These WSNs are deployed on a basis of two ways- structured or unstructured way. It is powered with solar alternative power in order to serve as a secondary battery source to overcome all power-based issues.
Underground WSNs
Unlike the terrestrial WSNs, these types of WSNs are deployed in areas below the terrestrial land, which makes the deployment cost high. These underground WSNs consist of numerous sensing nodes that are hidden underground. This type of WSN has low-grade batteries that possess less capability to recharge. It is not widely used as it has many limitations in the data gathering.
Multimedia WSNs
The Multimedia WSNs are the sensory devices that aim to gather data through the tracking of various environmental parameters by the integration of multimedia equipment like mics and cameras. It gathers data in the formats of image or audio or video depending upon the requirements. The area of deployment is diverse as it can be used in sectors like the military, health care, surveillance, etc.

What are the major elements of a Wireless Sensor Network?
The major elements of a typical WSN are listed one by one.
Sensors- Sensors or Sensory equipment are utilized to record the variables in any environmental conditions to gather the intended data. Signals from these sensors will get transformed into electrical typed signals.
Radio Nodes- These Radio Nodes are utilized to gather the data sensed from the sensory equipment and transmit those data to an access point in WLAN mode. It usually comprises a transceiver, microcontroller, power source, and external storage.
WLAN Access Point- An access point is established to gather the data that was wirelessly transmitted from the previous element, commonly via the web.
Assessment Software- The data that got transmitted from the established access point will be processed with any Assessment Software. The data from this software will be utilized to present the document to the consumer for further data processing.
