While using Wi-Fi would provide plenty of throughput, the receivers are energy hungry and, thus, the radio time needs to be reduced. Previous research suggests to combine Wi-Fi with low-power technologies such as BLE for an energy efficient coordination of the Wi-Fi radios. Existing approaches focus on individual point-to-point routes whereas certain applications require concurrent transmissions. We evaluated the combination of BLE and Wi-Fi on the ESP32-S3 multi-radio microcontroller through detailed energy and throughput measurements. The results show that established BLE connections allow to activateWi-Fi quickly on-demand; the energy efficiency of the data transmission is significantly improved over previous works but the BLE connection setup is prohibitively slow. While the combination of BLE and Wi-Fi provides high throughput with good energy efficiency, careful design of the BLE-based signalling protocol is necessary to also achieve low latency.}, language = {en} } @misc{KarnapkeWalther, author = {Karnapke, Reinhardt and Walther, Karsten}, title = {Realizing Seamless Integration of Sensors and Actuators into the IoT}, series = {Science and Technologies for Smart Cities : 7th EAI International Conference, SmartCity360°, Virtual Event, December 2-4, 2021, Proceedings}, journal = {Science and Technologies for Smart Cities : 7th EAI International Conference, SmartCity360°, Virtual Event, December 2-4, 2021, Proceedings}, editor = {Paiva, Sara}, publisher = {Springer}, address = {Cham}, isbn = {978-3-031-06370-1}, issn = {978-3-031-06371-8}, doi = {10.1007/978-3-031-06371-8_44}, pages = {688 -- 701}, language = {en} } @misc{GraffKarnapke, author = {Graff, Daniel and Karnapke, Reinhardt}, title = {From Centralized Management of Robot Swarms to Decentralized Scheduling}, series = {2018 IEEE International Conference on Internet of Things and Intelligence System (IOTAIS)}, journal = {2018 IEEE International Conference on Internet of Things and Intelligence System (IOTAIS)}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-1-5386-7358-4}, doi = {10.1109/IOTAIS.2018.8600917}, pages = {141 -- 147}, language = {en} } @misc{GraffKarnapke, author = {Graff, Daniel and Karnapke, Reinhardt}, title = {Managing Swarms of Robots: From Centralized Scheduling to Decentralized Scheduling (work in progress)}, series = {17.

Current research projects are already exploring the potential of NVRAM, but they face a challenge when they want to evaluate the performance: The new hardware is not yet available. In this paper, we discuss why benchmark results which are gained on existing DRAM are insufficient for a prediction of the performance on NVRAM. Either existing instructions have to be changed or new ones have to be introduced. We further show that the bochs emulator can be used to build systems which resemble NVRAM, to predict the NVRAM's consequences, and it even allows a comparison of algorithms for NVRAM.}, language = {en} } @misc{KarnapkeNolte, author = {Karnapke, Reinhardt and Nolte, J{\"o}rg}, title = {Triangle Routing in Wireless Sensor Networks with Unidirectional Links Revisited - a Look at Different Scenarios}, series = {International Journal on Advances in Networks and Services}, volume = {17}, journal = {International Journal on Advances in Networks and Services}, number = {1/2}, issn = {1942-2644}, pages = {72}, abstract = {Experiments with wireless sensor networks have shown that links are often asymmetric or unidirectional.
