This represents a serious problem for many routing protocols, which often depend on bidirectional links. Routing protocols that can use unidirectional links often induce a high overhead. To overcome this problem we introduced Unidirectional Link Triangle Routing, a routing protocol, which uses neighborhood information, gathered actively or passively, to route around unidirectional links. In this paper, we describe Unidirectional Link Triangle Routing in further detail and present additional evaluation results from different application scenarios.}, language = {en} } @misc{KarnapkeNolte, author = {Karnapke, Reinhardt and Nolte, J{\"o}rg}, title = {Unidirectional Link Triangle Routing for Wireless Sensor Networks}, series = {SENSORCOMM 2013, The Seventh International Conference on Sensor Technologies and Applications, Barcelona, Spain}, journal = {SENSORCOMM 2013, The Seventh International Conference on Sensor Technologies and Applications, Barcelona, Spain}, publisher = {IARIA}, isbn = {978-1-61208-296-7}, pages = {7 -- 14}, abstract = {Experiments with wireless sensor networks have shown that asymmetric and unidirectional links do not only exist, but are indeed quite common.

Still, most of today's routing protocols ignore their existence or try to remove their implications. Also, links are not stable over time, and routes become unusable often, resulting in a need for new routing protocols that can handle highly dynamic links and use unidirectional links to their advantage. In this paper, we present BuckshotDV, a routing protocol which is resilient against link fluctuations and uses the longer reach of unidirectional links to increase its performance. Furthermore, its distance vector nature makes it scalable for large sensor networks.}, language = {en} } @misc{KarnapkeNolteMank, author = {Karnapke, Reinhardt and Nolte, J{\"o}rg and Mank, Stephan}, title = {An Adaptive TDMA based MAC Protocol for Mobile Wireless Sensor Networks}, series = {International Conference on Sensor Technologies and Applications, SENSORCOMM 2007, Valencia, Spain, October 14 - 20}, journal = {International Conference on Sensor Technologies and Applications, SENSORCOMM 2007, Valencia, Spain, October 14 - 20}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-0-7695-2988-2}, pages = {62 -- 69}, language = {en} } @misc{KarnapkeNolteSenner, author = {Karnapke, Reinhardt and Nolte, J{\"o}rg and Senner, Tobias}, title = {A Combined Routing Layer for Wireless Sensor Networks and Mobile Ad-Hoc Networks}, series = {The Second International Conference on Sensor Technologies and Applications (SENSORCOMM 2008), 25 - 31 August 2008, Cap Esterel, France}, journal = {The Second International Conference on Sensor Technologies and Applications (SENSORCOMM 2008), 25 - 31 August 2008, Cap Esterel, France}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-0-7695-3330-8}, pages = {147 -- 153}, language = {en} } @misc{KarnapkeNolteWalther, author = {Karnapke, Reinhardt and Nolte, J{\"o}rg and Walther, Karsten}, title = {An Existing Complete House control System Based on the REFLEX Operating System: Implementation an Experiences over a Period of 4 Years}, series = {13th IEEE International Conference on Emerging Technologies and Factory Automation, ETFA 2008, Hamburg, Germany}, journal = {13th IEEE International Conference on Emerging Technologies and Factory Automation, ETFA 2008, Hamburg, Germany}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-1-4244-1506-9}, pages = {40 -- 45}, language = {en} } @misc{KarnapkeNolteWaltheretal., author = {Karnapke, Reinhardt and Nolte, J{\"o}rg and Walther, Karsten and Sieber, Andr{\´e}}, title = {Using Preemption in Event Driven Systems with a Single Stack}, series = {The Second International Conference on Sensor Technologies and Applications (SENSORCOMM 2008), 25 - 31 August 2008, Cap Esterel, France}, journal = {The Second International Conference on Sensor Technologies and Applications (SENSORCOMM 2008), 25 - 31 August 2008, Cap Esterel, France}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-0-7695-3330-8}, pages = {384 -- 390}, 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} }
