Experiment Control and Monitoring System for LOG-a-TEC Testbed

Abstract

The LOG-a-TEC testbed is a combined outdoor and indoor heterogeneous wireless testbed for experimentation with sensor networks and machine-type communications, which is included within the Fed4FIRE+ federation. It supports continuous deployment principles; however, it is missing an option to monitor and control the experiment in real-time, which is required for experiment execution under comparable conditions. The paper describes the implementation of the experiment control and monitoring system (EC and MS) as the upgrade of the LOG-a-TEC testbed. EC and MS is implemented within existing infrastructure management and built systems as a new service. The EC and MS is accessible as a new tab in sensor management system portal. It supports several commands, including start, stop and restart application, exit the experiment, flash or reset the target device, and displays the real-time status of the experiment application. When nodes apply Contiki-NG as their operating system, the Contiki-NG shell tool is accessible with the help of the newly developed tool, giving further experiment execution control capabilities to the user. By using the ZeroMQ concurrency framework as a message exchange system, information can be asynchronously sent to one or many devices at the same time, providing a real-time data exchange mechanism. The proposed upgrade does not disrupt any continuous deployment functionality and enables remote control and monitoring of the experiment. To evaluate the EC and MS functionality, two experiments were conducted: the first demonstrated the Bluetooth Low Energy (BLE) localization, while the second analysed interference avoidance in the 6TiSCH (IPv6 over the TSCH mode of IEEE 802.15.4e) wireless technology for the industrial Internet of Things (IIoT).

UMBRELLA: A One-Stop Shop Bridging the Gap From Lab to Real-World IoT Experimentation

“…Wireless Sensor Networks: INDRIYA2 [18], w-ILal [12], and Log-a-TEC [19] testbeds operate as wireless sensor networks providing access to various air quality monitoring sensors, e.g., humidity, temperature, pressure, etc. The idea is that the sensor data collected can be exchanged via an LPWAN interface (usually Bluetooth) and used for postprocessing by the end-users.…”

“…The users interact with UMBRELLA via a custom-built portal that provides role-based access to the different resources and testbeds. Visualisation of the collected data is built upon dashboards served with Grafana 19 . Several services are provided to ensure that the use case requirements are met.…”
