A scalable approach for periodic traffic scheduling in IEEE 802.15.4DSME networks The IEEE 802.15.4 standard contains the specifications of protocols that are suitable for industrial applications. Each of them is tailored for a specific industrial domain. One of these protocols is the Deterministic and Synchronous Multichannel Extension (DSME), which targets general industrial and commercial application domains. The DSME protocol extends the classic IEEE 802.15.4 protocol, overcoming the limitation on the maximum number of Guaranteed Time Slots (GTSs) and providing for channel diversity to increase network robustness. However, the DSME protocol suffers from scalability problems due to the rigid structure of the DSME multisuperframe, which in large networks does not allow to handle GTSs in an efficient way. To overcome this limitation, this work proposes the Shared DSME, an approach to handle the GTSs within the multisuperframe in an efficient way, thus increasing the scalability of the DSME protocol.

Schedulability Analysis and GCL Computation for TimeSensitive Networks Industrial automation networks are composed of cyberphysical systems where frame delays and jitter influence significantly the quality of communication between control and field devices. Due to these constraints, such systems are often served by dedicated Fieldbus networks which are different from networks for enterpriselevel connectivity. However, with the introduction of Timesensitive Networking standards which are already integrated into IEEE 802.1Q2018 standards in essential parts, the long expected single converged network for anytype communication in the field, control, and enterprise level is within reach. With it, comes the challenge of synthesizing schedules to obtain parameters for configuring the network bridges for timetriggered communication services.This paper provides a scheduling verification, and Gate Control event computation algorithm focused on asserting the viability of scheduling communication services for multiple independent periodic Talker applications on IEEE 802.1Q Time Sensitive Networks as well as the computation of Gate Control Lists for the bridges.
