Deterministic schedule and Monitoring Software
Schedule map for resources allocation
•A device requiring periodical transmissions can apply for EGTS slots•In this system, through appropriate arrangement of the EGTS slots, deterministic communication for some critical sensors can be provided. • The schedule map based on EGTS proposal was formed and shown in the monitoring software.

Conclusion
• IEEE 802.15.4e/EGTS solution works well for industrial application as:
– Channel Hopping and multi-superframe in ECFP, improve the capacity of dedicated bandwidth
– The dedicated transmission slot is very useful for industrial applications, because industrial applications usually need deterministic schedule
