This is an error-prone and complex task given the size, heterogeneity, and mobility of prevailing cyber-physical systems. We introduce an application model that allows the application developers to take a physical perspective. By means of this model, the programmers describe desired observations and influences with respect to the physical world without directly referencing physical devices. We present an additional model for a runtime environment that transparently utilizes the available physical devices to reach the application developers' targets. We show that an implementation of our models is functional via simulation.}, language = {en} } @misc{RottaChatharajupalliNaumannetal., author = {Rotta, Randolf and Chatharajupalli, Navya Sneha and Naumann, Billy and Schulz, Julius and Karnapke, Reinhardt and Werner, Matthias and Nolte, J{\"o}rg}, title = {Demo: B.A.T.M.A.N. mesh routing on ultra low-power IEEE 802.11 modules}, series = {2024 IEEE 49th Conference on Local Computer Networks (LCN)}, journal = {2024 IEEE 49th Conference on Local Computer Networks (LCN)}, publisher = {IEEE}, isbn = {979-8-3503-8800-8}, issn = {2832-1421}, doi = {10.1109/LCN60385.2024.10639789}, pages = {4}, abstract = {When implementing multi-hop mesh network protocols, efficient direct communication, route discovery, and route repair are crucial to achieve high network throughput.

We implemented the B.A.T.M.A.N. mesh protocol on the popular Espressif ESP32 along with a novel hybrid rate adaptation for the selection of efficient routes. In this demo we showcase challenges and solutions related to the implementation on ESP32 and how the hybrid rate adaptation improves end-to-end throughput.}, language = {en} } @inproceedings{SieberKarnapkeNolte, author = {Sieber, Andr{\´e} and Karnapke, Reinhardt and Nolte, J{\"o}rg}, title = {From Energy Accounting to Energy Management}, series = {13.

Mostly batteries are used, which are vulnerable to temperature and non-linear effects. Additionally, variations within the hardware or induced by the software make the prediction of the available and consumed energy a complicated task. To reach certain lifetime goals under these influences, online energy management is necessary. For a fine-grained management on the level of individual sub-tasks, it is necessary to know where in the system the energy is consumed. In this work, we extend our online energy accounting approach to enable online energy management. We present ways to control application and device behavior, and, thus, energy using energy budgets. First experiments yield promising results, reaching their lifetime goals while maintaining a high application quality.}, language = {en} } @misc{SieberKarnapkeNolteetal., author = {Sieber, Andr{\´e} and Karnapke, Reinhardt and Nolte, J{\"o}rg and Martschei, Thomas}, title = {Using Sensor Technology to Protect an Endangered Species: A Case Study}, series = {2011 IEEE 36th Conference on Local Computer Networks (LCN), Bonn, Germany, 4 - 7 October 2011, vol. 2}, journal = {2011 IEEE 36th Conference on Local Computer Networks (LCN), Bonn, Germany, 4 - 7 October 2011, vol. 2}, publisher = {IEEE}, isbn = {978-1-61284-926-3}, pages = {1044 -- 1047}, language = {en} }
