Types of Wireless Sensor Networks

Wireless Sensor Networks (WSNs) is a network of sensors that can monitor and record the environmental conditions and collect the data. Environmental conditions such as pressure, sound, pollution level, wind speed, and temperature are sensed by these networks and through them, they send data to the assigned location. To know all the Types of Wireless Sensor Networks, keep reading this article till the end.
These sensors are usually deployed at remote locations. Because of the ubiquity of the sensors, Wireless Sensor Networks are sometimes called ubiquitous sensors.
The wireless sensor network consists of base stations and from hundreds to thousands of nodes (wireless sensors). This was originally designed for the purpose to facilitate military operations but now it has many purposes including health care, air pollution, forest fire, water quality, machine health, water waste, structural health, greenhouse monitoring, and natural disaster prevention, landslide detection, data logging, wine production, and threat detection.
There are several types of Wireless Sensor Networks

1. Mobile WSNs
2. Multimedia WSNs
3. Terrestrial WSNs
4. Underground WSNs
5. Underwater WSNs

However convenient, WSNs are vulnerable to external attacks that can impair its’ operations. The nodes need to be deployed in remote and hostile areas and their lifetime is connected with the battery load; nodes will remain active to use as long as the batteries run out. Several protocols need to be designed to give the nodes a long life.
