A Scalable Data Acquisition Architecture in Web-Based IOT

The data acquisition system in Web-based IOT needs to consider not only the requirements of the daily routine analysis of the data, but also the requirements from the real-time reaction of an emergency, which presents a dilemma for system design. This paper presents scalable distributed data acquisition system architecture SCADA, which can extend the system capability temporally using extra resources to meet the demands. Based on the traditional Master-Worker model, the system makes uses of the executors for task execution and resource allocation and can execute the tasks efficiently. The experiment proves the scalability of SCADA.
