TDM Edge Gateway: A Flexible Microservice-Based Edge Gateway Architecture for Heterogeneous Sensors

How to effectively handle heterogeneous data sources is one of the main challenges in the design of large-scale research computing platforms to collect, analyze and integrate data from IoT sensors. The platform must seamlessly support the integration of myriads of data formats and communication protocols, many being introduced after the platform has been deployed. Edge gateways, devices deployed at the edge of the network near the sensors, communicate with measurement stations using their proper protocol, receive and translate the messages to a standardized format, forward the data to the processing platform and provide local data buffering and preprocessing. In this work we present the TDM Edge Gateway architecture, which we have developed to be used in research contexts to meet the requirements of being self-built, low-cost, and compatible with current or future connected sensors.
