Abstract In this paper, a net message scheduling method called Traffic-Aware Message Scheduling (TAMS) on shared timeslots of ISA100.11a is proposed to enhance real-time performance. In conventional approaches, sending sporadic messages always causes a lot of collisions. It leads to poor performances in real-time systems. In order to solve this problem, the proposed method in this paper divides end-nodes into parts, and them accesses the channel in the specific cycles when the provability of timeslots getting involved in collision exceeds a threshold. The simulation results show that the proposed method can improve the performance in terms of throughput and end-to-end delay.

Q) How to divide the node?

A) The node divided each group per 3 randomably

Q) How to assign the priority?

A) The priority is assigned uniformity and randomable
