  Abstract

As the development of IoT accelerated, the number of IoT connected devices has increased sharply, and the application areas of the IoT platform have also diversified. Naturally, new requirements have emerged in each field, and as a result, the environment in which IoT has to adapt has also diversified. However, there are opinions that the technology to satisfy the client’s requirements is insufficient, and various platforms using the current IoT protocol can not maximize the efficiency by simply using the protocol. As a result, protocols and platforms designed for the IoT environment have been controversial because of efficiency issues. Among them, MQTT, which is popular as IoT protocol, has been proved to be efficient in terms of battery consumption due to its lightweight message protocol. However, it is pointed out that the device has to maintain connection with the server even when communication is not needed.In this paper, we analyze the problems of MQTT based platform which is commonly used to solve these problems and suggest three solutions including MQTT Device Polling, Broker Persistence, Daymic Topic Generation and Dynamic Subscribe to improve the efficiency of using MQTT protocol.
