Coping with bursty traffic is a common yet challenging task in the industrial Internet of Things (IoT). For example, 6LoWPAN is a standard that defines the integration of LoWPAN with IPv6, by fragmenting large IPv6 packets into several smaller MAC‐layer packets. Therefore, it is necessary to envision message delivery mechanisms, which provide support for highly varying traffic. In this paper, we analyze sending multiple packets per guaranteed time slot (GTS) in IEEE 802.15.4 DSME to alleviate traffic during the contention‐access period (CAP) and increase the reliability in scenarios with bursty traffic. The evaluation shows that increasing parameter SO extends the network throughput beyond default operating conditions and also provides overprovisioning beneficial for delivering sporadic messages. A comparison with the transmission of a single packet per GTS demonstrates a reduction of the total number of transmitted CAP messages by 99% while increasing the packet reception ratio by 48% for bursts with 20 packets.
