 Wireless sensor networks, WSNs, are a type of network composed of small, low-cost sensors that can collect data in remote locations. They have been used for a variety of purposes such as environmental monitoring, healthcare, military operations, and industrial automation. WSNs offer many advantages over traditional networks, including lower cost, smaller size, and greater flexibility. However, they also come with some drawbacks, such as limited battery life and reliability issues due to the presence of wireless communication. Despite these challenges, WSNs continue to be used in a wide range of applications, such as environmental monitoring, healthcare, military operations, and industrial automation.
