Leveraging only the history of geographic movement patterns in the two-hop neighborhood, our algorithm is able to perform well in the absence of knowledge of social interaction between nodes and without detailed future schedule information. Representing previously visited locations as probability distributions encoded in an efficient vector, we formalize a heuristic for efficiently forwarding messages in disruption tolerant networks, implement a framework for comparing our approach with the state of the art, and evaluate key metrics, such as hop count and delivery rate, as well as energy consumption and battery depletion fairness on real world data. We are able to outperform the state of the art in human mobility based networks considerably in terms of energy usage per node, thereby extending data network availability further into areas devoid of otherwise necessary communication infrastructure.}, url = {fileadmin/papers/2011/2011-GlobeCom-bitsch-geoDTN.pdf}, misc2 = {Online}, address = {Piscataway, NJ, USA}, booktitle = {IEEE GLOBECOM 2011 - Next Generation Networking Symposium (GC'11 - NGN), Houston, Texas, USA}, organization = {IEEE}, event_place = {Houston, Texas, USA}, event_name = {IEEE GLOBECOM 2011 - Next Generation Networking Symposium (GC'11 - NGN)}, event_date = {5-9 December 2011}, language = {en}, ISBN = {978-1-4244-9268-8}, ISSN = {1930-529X}, reviewed = {1}, author = {Bitsch Link, J{\'o} Agila and Schmitz, Daniel and Wehrle, Klaus} } @Inproceedings { 2011-extremecom-bitsch-neighbordiscovery, title = {Perfect Difference Sets for Neighbor Discovery}, year = {2011}, month = {9}, day = {26}, pages = {1--6}, abstract = {We present an energy efficient neighbor discovery framework that enables Linux and TinyOS based systems to discover and connect to neighbors via IEEE 802.11 and IEEE 802.15.4, which are only available sporadically. Using quorum schemes, we schedule on and off times of the wireless transmitters, to guarantee mutual discovery with minimum power given a specific latency requirement. Neighbor discovery is fundamental to intermittently connected networks, such as disruption and delay tolerant networks and optimizing it, can lead to significant overall energy savings. Using perfect difference sets, our results indicate that we reduce the latency by up to 10 times at a duty cycle of 2\% compared to the state of the art. We further define and characterize our neighbor discovery scheme with respect to fairness for asymmetric energy scenarios. Using these results, we allow energy-harvesting applications to adjust neighbor discovery based on their current energy requirements as a well defined trade-off.}, keywords = {Neighbor Discovery; Sporadic Connectivity; Wireless Networks}, url = {fileadmin/papers/2011/2011-ExtremeCom-bitsch-NeighborDiscovery.pdf}, web_url = {http://www.cl.cam.ac.uk/\verb=~=fb375/extremecom/2011/program.html}, web_url2 = {http://dl.acm.org/citation.cfm?id=2414398\&CFID=194814085\&CFTOKEN=73001357}, misc2 = {Online}, editor = {Hui, Pan and Lindgren, Anders}, publisher = {ACM}, booktitle = {Proceedings of the 3rd Extreme Conference of Communication (ExtremeCom 2011), Manaus, Brazil}, event_place = {Manaus, Brazil}, event_name = {ExtremeCom 2011}, event_date = {26-30 September 2011}, language = {en}, ISBN = {978-1-4503-1079-6}, reviewed = {1}, author = {Bitsch Link, J{\'o} Agila and Wollgarten, Christoph and Schupp, Stefan and Wehrle, Klaus} } @Inproceedings { 2011-wirtz-chants, title = {Establishing Mobile Ad-Hoc Networks in 802.11 Infrastructure Mode}, year = {2011}, month = {9}, day = {23}, url = {fileadmin/papers/2011/2011-wirtz-chants.pdf}, misc = {Online}, publisher = {ACM}, address = {New York, NY, USA}, booktitle = {Proceedings of the ACM MobiCom Workshop on Challenged Networks (Chants 2011), Las Vegas, NV, USA}, event_place = {Las Vegas, NV, USA}, event_name = {ACM MobiCom Workshop on Challenged Networks (Chants 2011)}, event_date = {2011-09-23}, language = {en}, ISBN = {978-1-4503-0870-0}, DOI = {10.1145/2030652.2030666}, reviewed = {1}, author = {Wirtz, Hanno and Heer, Tobias and Backhaus, Robert and Wehrle, Klaus} } @Inproceedings { 2011-ipin-bitsch-footpath-long, title = {FootPath: Accurate Map-based Indoor Navigation Using Smartphones}, year = {2011}, month = {9}, day = {21}, pages = {1--8}, abstract = {We present FootPath, a self-contained, map-based indoor navigation system.

In practice, this makes MANETs hard to realize. While 802.11-compliant mobile devices implement the ad-hoc mode on the hardware layer, the software layer typically does not implement support for ad-hoc networking in terms of ad-hoc routing and name resolution protocols. Modern mobile operating systems, such as Android and iOS, even hide the inherent ad-hoc functionality of the wireless card through restrictions in the OS. In contrast to this, support for the 802.11 infrastructure mode is a commodity. We propose establishing ad-hoc networks using the 802.11 infrastructure mode. In MA-Fi (Mobile Ad-Hoc Wi-Fi), a small core of mobile router nodes (RONs) provides infrastruc-ture mode network access to mobile station nodes (STANs). As RONs also act as a station in infrastructure networks of other RONs, MA-Fi achieves multi-hop communication between RON and STAN devices in the overall network. We show the creation and operation of mobile ad-hoc networks using MA-Fi. We focus on mobility of RONs and STANs as well as topology control in the overall network.}, url = {fileadmin/papers/2011/2011-wirtz-wintech.pdf}, misc = {Online}, publisher = {ACM}, address = {New York, NY, USA}, booktitle = {Proceedings of the Sixth ACM International Workshop on Wireless Network Testbeds, Experimental evaluation and Characterization (WiNTECH 2011), Las Vegas, NV, USA}, event_place = {Las Vegas, Nevada, USA}, event_name = {The Sixth ACM International Workshop on Wireless Network Testbeds, Experimental evaluation and Characterization}, event_date = {2011-09-19}, language = {en}, ISBN = {978-1-4503-0867-0}, DOI = {10.1145/2030718.2030737}, reviewed = {1}, author = {Wirtz, Hanno and Backhaus, Robert and Hummen, Ren{\'e} and Wehrle, Klaus} } @Inproceedings { VaegsABW2011, title = {Efficient Power Management Using Out-of-Band Signaling}, year = {2011}, month = {9}, day = {16}, pages = {77-80}, abstract = {A tremendous amount of energy is wasted today, because computing devices are left running all the time even though they are needed only sporadically. Especially in office environments many devices (e.g., printers) are very rarely turned off, because they need to be available from time to time and because it is inconvenient having to switch them on and off manually. Existing solutions, such as Wake-on-LAN (WoL), provide support for managing the power consumption of the network devices remotely using an always-on data channel. However, these solutions are inefficient, because power to the network interface has to be maintained even when the host system is asleep just to ensure remote accessibility. We propose a Wireless Sensor Network (WSN) based out-of-band signaling architecture for network interfaces which minimizes the systems’ power consumption during the large idle periods when nobody is using them. This is done by separating the data and control channels on the Internet-enabled devices using a low-power out-of-band signaling channel based on battery driven, energy scavenging devices. Unlike existing solutions, which only allow parts of the system to go in sleep modes, our architecture allows the whole system, including the main power supply, to be shut down. Our initial investigation indicates a significant reduction in energy consumption of devices during idle times compared to the existing in-band signaling mechanisms such as WoL.}, keywords = {Energy Saving, Wireless Sensor Network, Out-of-Band Signalling}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2011/2011-vaegs-fgsn-ecocom.pdf}, misc2 = {Online}, booktitle = {Proceedings of the 10th GI/ITG KuVS Fachgespr{\"a}ch Drahtlose Sensornetze (FGSN), Paderborn, Germany}, institution = {RWTH Aachen University}, event_place = {Paderborn, Germany}, event_name = {10th GI/ITG KuVS Fachgespr{\"a}ch Drahtlose Sensornetze (FGSN11)}, event_date = {September 15-16, 2011}, language = {en}, reviewed = {1}, author = {Vaegs, Tobias and Alizai, Muhammad Hamad and Bitsch Link, J{\'o} Agila and Wehrle, Klaus} } @Inproceedings { 2011-ipsn-alizai-pad, title = {Probabilistic Addressing: Stable Addresses in Unstable Wireless Networks}, year = {2011}, month = {4}, url = {fileadmin/papers/2011/2011-ipsn-alizai-pad.pdf}, misc2 = {Online}, publisher = {ACM}, address = {New York, NY, USA}, booktitle = {Proceedings of the 10th ACM/IEEE International Conference on Information Processing in Sensor Networks (IPSN 2011), Chicago, IL, USA}, event_place = {Chicago, IL, USA}, language = {en}, ISBN = {978-1-60558-988-6}, reviewed = {1}, author = {Alizai, Muhammad Hamad and Vaegs, Tobias and Landsiedel, Olaf and G{\"o}tz, Stefan and Bitsch Link, J{\'o} Agila and Wehrle, Klaus} } @Poster { 2011-03-vomLehn-NSDI-PrivacyOnWeb, title = {Work in Progress: Uncovering the Privacy Implications of Web Usage [Poster]}, year = {2011}, month = {3}, note = {poster and abstract}, url = {fileadmin/papers/2011/2011-03-vomLehn-NSDI-PrivacyOnWeb.pdf}, misc2 = {Online}, booktitle = {8th USENIX Symposium on Networked Systems Design and Implementation (NSDI '11), Boston, MA, USA}, organization = {Usenix}, event_place = {Boston, MA, USA}, event_name = {NSDI}, event_date = {March 30 – April 1, 2011}, state = {accepted}, language = {en}, reviewed = {1}, author = {vom Lehn, Hendrik and Bitsch Link, J{\'o} Agila and Wehrle, Klaus} }
