Caching-Aided Collaborative D2D Operation for Predictive Data Dissemination in Industrial IoT
Industrial automation deployments constitute challenging environments where
moving IoT machines may produce high-definition video and other heavy sensor
data during surveying and inspection operations. Transporting massive contents
to the edge network infrastructure and then eventually to the remote human
operator requires reliable and high-rate radio links supported by intelligent
data caching and delivery mechanisms. In this work, we address the challenges
of contents dissemination in characteristic factory automation scenarios by
proposing to engage moving industrial machines as device-to-device (D2D)
caching helpers. With the goal to improve reliability of high-rate
millimeter-wave (mmWave) data connections, we introduce the alternative
contents dissemination modes and then construct a novel mobility-aware
methodology that helps develop predictive mode selection strategies based on
the anticipated radio link conditions. We also conduct a thorough system-level
evaluation of representative data dissemination strategies to confirm the
benefits of predictive solutions that employ D2D-enabled collaborative caching
at the wireless edge to lower contents delivery latency and improve data
acquisition reliability
A Periodicity Metric for Assessing Maintenance Strategies
Organised by: Cranfield UniversityThe maintenance policy in manufacturing systems is devised to reset the machines functionality
in an economical fashion in order to keep the products quality within acceptable levels. Therefore,
there is a need for a metric to evaluate and quantify function resetting due to the adopted
maintenance policy. A novel metric for measuring the functional periodicity has been developed
using the complexity theory. It is based on the rate and extent of function resetting. It can be used
as an important criterion for comparing the different maintenance policy alternatives. An industrial
example is used to illustrate the application of the new metric.Mori Seiki – The Machine Tool Company; BAE Systems; S4T – Support Service Solutions: Strategy and Transitio
