Abstract
Research and development on the Internet of Things (IoT) has been promoted actively. However, when a large number of tiny data blocks are transferred over the Internet conventionally, some critical problems such as large overheads for legacy protocols and their processing power for communication equipment are highlighted. To solve these problems, MQTT has been discussed actively in academic societies and standardization organizations. However, it is not reasonable to use the MQTT to transfer large files, e.g., video files from surveillance footage. This paper proposes new mechanisms for cooperation between MQTT and FTP for data blocks of any size. This paper also reports the reasonability of this mechanism through prototyping.
