An agile development platform for Internet-of-things applications in cloud environment

Beginners have been facing challenges in IoT development and applications due to the existing hardware diversity and complexity. The deployment under current circumstances proves to be inefficient and error-prone. To address this issue, an agile development platform for IoT in cloud environment is proposed. The platform is designed to achieve functions including the cross-device, interpretive execution, online running, etc. To implement the online code downloading, a fine-tuned MQTT protocol is adopted. In addition, a set of experiment kits are designed as a supporting system, all of which serve the functions of online coding and the real-time running on devices. To reduce risk of the access of unauthorized devices and the leak of user information, an authentication method based on the TEA encryption algorithm is presented. Compared with existing schemes, the platform has the advantages of simplicity, friendliness, and can improve the efficiency of IoT development.
