Abstract

This paper reports on experimental results of a wireless sensor network set up in an industrial automation facility at a Swedish mining company. It illustrates that the new ZigBee standard performs well even in heavy industrial environments. The main focus is on timing issues and achieving synchronized duty cycling. A simple synchronization algorithm is devised and shown to be sufficient to meet strict power consumption requirements.
