Abstract—Wireless technologies combined with advanced
computing are changing industrial communications. Industrial
wireless networks can improve the monitoring and the control
of the entire system by jointly exploiting massively interacting
communication and distributed computing paradigms. In this
paper, we develop a wireless cloud platform for supporting
critical data publishing and distributed sensing of the surrounding
environment. The cloud system is designed as a
self-contained network that interacts with devices exploiting the
time synchronized channel hopping protocol (TSCH), supported
by WirelessHART (IEC 62591). The cloud platform augments
industry-standard networking functions as it handles the delivery
(or publishing) of latency and throughput-critical data by implementing
a cooperative-multihop forwarding scheme. In addition,
it supports distributed sensing functions through consensus-based
algorithms. Experimental activities are presented to show the feasibility
of the approach in two real industrial plant sites representative
of typical indoor and outdoor environments. Validation of
cooperative forwarding schemes shows substantial improvements
compared with standard industrial solutions. Distributed sensing
functions are developed to enable the autonomous identification
of recurring cochannel interference patterns.
