kenttäverkot

Kenttäverkot, often translated as field networks or sensor networks, refer to a decentralized system of spatially distributed autonomous devices called sensors, used to monitor physical or environmental conditions. These sensors collect data such as temperature, sound, vibration, pressure, motion, or pollutants, and cooperatively pass their data through the network to a main location. The development of kenttäverkot has been driven by advancements in wireless communication, embedded systems, and microelectromechanical systems (MEMS).

A typical kenttäverkko consists of nodes, which are individual sensor devices. Each node is equipped with a sensing unit, a processing unit, a transmitter/receiver, and a power source. The nodes communicate with each other wirelessly, often using low-power, short-range protocols. Data can be routed through multiple nodes to reach a base station or sink, which then aggregates and processes the information. The architecture can be flat or hierarchical, depending on the application's requirements for scalability and efficiency.

Applications for kenttäverkot are diverse and span numerous fields. In environmental monitoring, they are used for tracking weather patterns, detecting pollution, and observing wildlife. In agriculture, they help optimize irrigation and fertilization by monitoring soil conditions and crop health. Industrial applications include monitoring machinery performance, ensuring safety, and managing assets. Military and defense sectors utilize kenttäverkot for surveillance, reconnaissance, and battlefield awareness. The growth of the Internet of Things (IoT) has further accelerated the adoption and development of kenttäverkko technologies, enabling a wide range of smart applications.
