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. At Sensorcomm 2014, we presented 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. This paper is an extended version which adds some implementation details and the evaluation of BuckshotDV in two more application scenarios.}, language = {en} } @misc{LopacinskiNolteBuechneretal., author = {Lopacinski, Lukasz and Nolte, J{\"o}rg and B{\"u}chner, Steffen and Brzozowski, Marcin and Kraemer, Rolf}, title = {Design and Implementation of an Adaptive Algorithm for Hybrid Automatic Rrepeat Request}, series = {18th International Symposium on Design and Diagnostics of Electronic Circuits \& Systems (DDECS), Belgrade/Serbia, 2015}, journal = {18th International Symposium on Design and Diagnostics of Electronic Circuits \& Systems (DDECS), Belgrade/Serbia, 2015}, publisher = {IEEE}, doi = {10.1109/DDECS.2015.32}, pages = {263 -- 266}, language = {en} } @misc{KarnapkeLohsNolte, author = {Karnapke, Reinhardt and Lohs, Stefan and Nolte, J{\"o}rg}, title = {How to ruin Sensor Network Performance using Duplicate Suppression}, series = {Sensor Systems and Software, 5th International Conference, S-CUBE 2014, Coventry, UK, October 6-7, 2014, Revised Selected Papers}, journal = {Sensor Systems and Software, 5th International Conference, S-CUBE 2014, Coventry, UK, October 6-7, 2014, Revised Selected Papers}, editor = {Kanjo, Eiman and Trossen, Dirk}, publisher = {Springer}, address = {Cham}, isbn = {978-3-319-17135-7}, pages = {20 -- 29}, language = {en} } @misc{BeyerLohsNolteetal., author = {Beyer, Sandra and Lohs, Stefan and Nolte, J{\"o}rg and Karnapke, Reinhardt and Siegemund, Gerry}, title = {Self-Stabilizing Structures for Data Gathering in Wireless Sensor Networks}, series = {SENSORCOMM 2015, The Ninth International Conference on Sensor Technologies and Applications, August 23-28, 2015 Venice, Italy}, journal = {SENSORCOMM 2015, The Ninth International Conference on Sensor Technologies and Applications, August 23-28, 2015 Venice, Italy}, publisher = {IARIA}, isbn = {978-1-61208-425-1}, pages = {71 -- 76}, language = {en} } @misc{BuechnerNolteKraemeretal., author = {B{\"u}chner, Steffen and Nolte, J{\"o}rg and Kraemer, Rolf and Lopacinski, Lukasz and Karnapke, Reinhardt}, title = {Challenges for 100 Gbit/s End to End Communication: Increasing Throughput Through Parallel Processing}, series = {40th Annual IEEE Conference on Local Computer Networks, 2015, Clearwater Beach Florida}, journal = {40th Annual IEEE Conference on Local Computer Networks, 2015, Clearwater Beach Florida}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-1-4673-6770-7}, doi = {10.1109/LCN.2015.7366337}, pages = {398 -- 401}, abstract = {Today's applications and services become more dependent on fast wireless communication, for the upcoming years data-rate demands of 100Gbit/s can be easily expected.

While most of the research tackles the challenges regarding the transmission technology from the physical layer up to base-band processing, we focus on the challenges concerning the handling of that vast amount of data. The overall goal is to bring together the transmission technology with the operating system to create a suitable end-to-end communication solution.
