Performance Evaluation of Multi‐hop Wireless HART Network on a Real‐life Testbed
Journal Title: Transactions on Networks and Communications - Year 2018, Vol 6, Issue 1
Abstract
Advances in WirelessHART standard in industrial control systems have led to performance evaluation and security analysis in both real‐world testbeds as well as in controlled lab environments. We have conducted months‐long experiments with WirelessHART network in a multi‐hop setting in our laboratory. Latency, stability, and reliability have been used as metrics to measure performance of individual links and the overall network for five hops and seven hops. We have deliberately deviated from following the best practices in designing the topology to study network performance under strained conditions. In addition to using metrics as defined in WirelessHART literature, we have also studied network stability over multiple hops with single paths. Our findings show that having at least one low stability link can have an impact on multihop stability, while still maintaining a very high overall network reliability of 99.98% or higher. Details of the experiment along with results and lessons learned are presented in the paper.
