    BASE MoVE - A Basis for a Future-proof IoT Sensor
    (INFORMATIK 2020, 2021) Akelbein, Jens-Peter; Beckmann, Kai; Hoss, Mario; Schneider, Samuel; Seyfarth, Stefan; Thoss, Marcus
    For a long time, the Internet of Things was considered the vision of interconnecting every device, leading to fundamentally new and pervasive application scenarios. In practice, however, the projected growth and realisation of IoT scenarios is often impeded by practical problems. The BASE MoVE research project, a cooperation between universities and industrial partners, took a holistic look at requirements and inhibitors for investing in IoT solutions, using Ambient Assisted Living as an application domain example. The perspectives of all stakeholders involved were taken into account during the design of a solution architecture, from the user to the manufacturer to the service provider and housing association. This paper presents the resulting modular base platform for IoT applications. Power supply through battery and energy harvesting reduces installation costs. The use of open source software and the support of several common smart home protocols also prevents a lock-in effect and dependency on a single manufacturer. This makes it possible to protect investments from market-driven changes from one manufacturer's ecosystem to another. Here, the paper takes an in-depth look into the choice of protocols. Over-the-air updates allow for secure operation as well as remote maintenance, no longer requiring expensive in-person maintenance. Finally, the manufacturing of the solution as a hardware module, as realised in BASE MoVE, also allows for easier creation and certification of new sensor devices in a company's product portfolio. To evaluate the developed solution, an apartment was equipped with different sensor devices, and a smart home scenario was implemented. The feasibility study could demonstrate that it is indeed possible to create a base platform that meets today's requirements of the stakeholders involved and allows for a sustainable, future-proof usage by offering adaptability to new technologies. In addition to the scientific results, the project also gave an assessment about component maturity and cost, which is valuable for the commercial project partner and its market entry strategy.

    A Decade of Energy Awareness Technology Evolution for Sensor Nodes
    (INFORMATIK 2020, 2021) Thoss, Marcus
    Energy awareness is an important aspect of the design of sensor node hard-and software, particularly for battery-powered or energy-harvesting node architectures. Architectural design choices of such systems must regard a multitude of aspects, including size, weight, memory and processing power. Therefore, energy-related design aspects have in recent years become a feature that is being honoured throughout sensor node design. As a result, various technological solutions and strategies have evolved to facilitate energy awareness and energy management aspects. This paper looks back at the evolution of sensor node technology during the 2010s. In the course of research activities, the state of the art of research and industrial solutions aiming at improving the support of energy awareness was being monitored. Advances were observed for various aspects and levels of relevant technological facets, including electronic measurement and control circuitry, harvesting facilities, power-saving mechanisms at both hard-and software level, energy management strategies and algorithms, networking aspects, and advances and extensions related to operating systems for sensor nodes. A conclusion of these observations, given in this paper, identifies technological increments, leaps and sidesteps that have occurred along the way. For the overall time span of the decade observed, a short qualitative and quantitative analysis of the technological advances achieved is presented, including typical examples of actual sensor node designs. The paper concludes with an outlook on further evolution of advances in energy awareness technology for sensor nodes to be expected in the near future and to be desired in the long run.
