Abstract

The ability of wireless sensor networks, or WSNs, to monitor and collect data from the actual environment has led to their increasing popularity across many sectors. This abstract provides a brief summary of WSNs, talking about its main features, applications, and issues. Distributed networks of autonomous sensors that communicate with one another and keep tabs on the physical world constitute what are known as WSNs. With their built-in sensing, computing, and wireless communication capabilities, these sensors can exchange data with each other and a central processing unit. Because these networks are wireless, no physical connections are required, making them perfect for remote or inaccessible areas. Environmental monitoring, healthcare, agriculture, industrial automation, and military surveillance programmes are just a few of the many diverse areas that find use for WSNs. WSNs have potential applications in environmental monitoring for collecting data on a range of environmental variables, including humidity, pollution levels, and temperature. In healthcare, they facilitate patient monitoring and provide support for the treatment of chronic ...
