Wireless Networks Questions Medium
A wireless sensor network (WSN) is a network of interconnected sensors that are wirelessly connected to each other and can communicate with a central base station or gateway. These sensors are typically small, low-power devices that are equipped with various types of sensors to collect data from the environment. The data collected by the sensors can include temperature, humidity, pressure, light, sound, and motion, among others.
The sensors in a WSN are usually deployed in a specific area or environment, such as a building, a field, or an industrial facility, to monitor and gather information about the physical or environmental conditions. They can be stationary or mobile, depending on the application requirements.
The communication between the sensors in a WSN is typically achieved through wireless protocols, such as Wi-Fi, Bluetooth, Zigbee, or LoRaWAN. These protocols enable the sensors to transmit the collected data to the base station or gateway, which acts as a central hub for data processing and analysis.
WSNs have numerous applications in various fields, including environmental monitoring, agriculture, healthcare, industrial automation, and smart cities. They provide real-time data collection, remote monitoring, and control capabilities, enabling efficient and cost-effective solutions for a wide range of applications.
Overall, a wireless sensor network is a network of interconnected sensors that wirelessly communicate with each other to collect and transmit data from the environment for monitoring and analysis purposes.
