Towards Data Aggregation on Multi-Senso...

Wireless transducer nodes often provide more than one sensor channel. The application specific requirements on these individual channels can be quite different, e.g. in terms of measurement rate and permitted latency. In order to allow for corresponding power consumption optimization for a given application, we propose an extension of the ISO/IEC/IEEE 21450 Transducer Electronic Datasheet. Based on this proposed data aggregation concept, the individual measurement rate and the permitted latency can be adjusted. In addition, potential retransmissions due to losses on the wireless communication channel can be considered. The proposed concept is showcased in an industrial condition monitoring example.
