Abstract [en]

TDMA has been resumed for industrial wireless sensor network (IWSN) like WirelessHART and ISA 100.11a recently, because TDMA is suitable for periodic traffic which is predictable to pre-assign. However, for random traffic TDMA degenerates to inefficient slotted ALOHA. In our previous work, we propose a new medium access control (MAC) scheme called discrete-time CSMA (DT-CSMA) that can be applied to improve the efficiency of TDMA-based system that transmits periodic and random traffic. In this paper, we give a model to evaluate system throughput for DT-CSMA. An analysis of typical scenario shows DT-CSMA improves the throughput by 100%. We also build a model to evaluate synchronization influence on DT-CSMA, which indicates that the influence is limited.
