Abstract:
This paper addresses an important issue for user friendliness for network operators and scalability of environmental measurement networks: Plug and Measure. On Sensor Level, this is comparable with connecting an USB Keyboard to a PC: The operating system receives the event that a new device has been discovered and tries to install its drivers to integrate its new functionality. Similarly, a data acquisition system in a measuring station shall be able to recognize new sensors at plug in and automatically start exchanging configuration data and measurements.
On Application Level, Plug and Measure covers the scalability issue. In measurement networks, merely receiving values is not enough. Usually, adding a new sensor implies more than just saving its measurements to a database. Questions about the value processing to mean values, the aggregation of values, and the destination as well as the conditions of alerts need to be answered. In order to know what to do with values, a network needs to know about the semantics. It needs to know about units and the types of measurements. This is the principal prerequisite for scalability.
