abstract = "As the number of IoT devices with high performance has increased, so many streaming services using IoT devices have been developed. One of the major challenges in the realization of the services is delay. MQTT and CoAP are usually used for such services because these protocols can support the pub/sub architecture. However, those protocols use only one broker or server. Thus, they may give poor performance, when the number of the topics associated with the IoT streaming service gets larger. In this paper, we propose a new scheme for distributed, interoperable architecture among servers, in which two or more servers can create a group and a client can view the group as a powerful server. By implementation and experimentation, we can see that the proposed scheme provides the performance gains over the existing MQTT and CoAP schemes in terms of total delay by approximately 45% where the number of topics is 500 in the IoT streaming services.",
