Design and Implementation of IoT Server Platform with Applications.

Nowadays, rapid developments of technologies have increased possibilities of realizing where collaborations and integrations of various are essential. However, IoT application systems have often been designed and deployed independently without considering the standards of devices, logics, and data communications. In this paper, we present the design and implementation of the called for integrating IoT application systems using standards. offers environments with functions for data aggregations, synchronizations, and classifications with . Moreover, functions can be easily implemented. Data from devices for different sensors can be accepted directly and through network connections, which will be used in real-time for user interfaces, text files, and access to other systems through services. For evaluations of , we implemented the platform and integrated five IoT application systems, namely, the , the , the , the , and the . When compared with existing research on IoT platforms, the proposed IoT application server platform offers higher flexibility and interoperability with the functions for IoT device managements, data communications, decision making, synchronizations, and filters that can be easily integrated with external programs or IoT applications without changing the codes. The results confirm the effectiveness and efficiency of the proposal.
