With the dramatic increase in Internet of Things (IoT) related messaging volume, message queue systems are highly required for both interoperability among devices, as well as for control message traffic between devices and heterogeneous back-end systems (BES). When connected BES issue several dequeue requests to the message queue and no message is available, the frequency of missed-dequeues increases, which causes a degradation of the maximum throughput. Therefore, we propose the retry dequeue-request scheduling (RDS) method that decreases the number of dequeue requests from the BES by delaying the replies to the BES when missed-dequeues occur. Simulation and experimental evaluations show that the throughput of the RDS method achieves 180% of that of the conventional dequeue method.
