As opposed to the existing approaches, which checkpoint complete program state, the proposed techniques keep track of modified RAM locations to incrementally update the retained state in secondary memory, significantly reducing checkpointing overhead both in terms of time and energy. /fileadmin/misc/2016/2016-ahmed-sensys-poster-incremental.pdf http://dl.acm.org/citation.cfm?id=2996701 2016-11-20 http://sensys.acm.org/2016/ Online ACM Proceedings of the 14th ACM Conference on Embedded Networked Sensor Systems (SenSys 2016), Stanford, CA, USA Stanford, CA, USA Sensys '16 November 14-16, 2016 en 978-1-4503-4263-6/16/11 http://dx.doi.org/10.1145/2994551.2996701 1 SaadAhmed HassanKhan Junaid HaroonSiddiqui Jó AgilaBitsch Link Muhammad HamadAlizai inproceedings 2016-ackermann-healthcom-eeg-emotion 2016 9 14 159--164 Automatic emotion recognition is an interdisciplinary research field which deals with the algorithmic detection of human affect, e.g. anger or sadness, from a variety of sources, such as speech or facial gestures. Apart from the obvious usage for industry applications in human-robot interaction, acquiring the emotional state of a person automatically also is of great potential for the health domain, especially in psychology and psychiatry. Here, evaluation of human emotion is often done using oral feedback or questionnaires during doctor-patient sessions. However, this can be perceived as intrusive by the patient. Furthermore, the evaluation can only be done in a non-continuous manner, e.g. once a week during therapy sessions. In contrast, using automatic emotion detection, the affect state of a person can be evaluated in a continuous non-intrusive manner, for example to detect early on-sets of depression. An additional benefit of automatic emotion recognition is the objectivity of such an approach, which is not influenced by the perception of the patient and the doctor. To reach the goal of objectivity, it is important, that the source of the emotion is not easily manipulable, e.g. as in the speech modality. To circumvent this caveat, novel approaches in emotion detection research the potential of using physiological measures, such as galvanic skin sensors or pulse meters. In this paper we outline a way of detecting emotion from brain waves, i.e., EEG data. While EEG allows for a continuous, real-time automatic emotion recognition, it furthermore has the charm of measuring the affect close to the point of emergence: the brain. Using EEG data for emotion detection is nevertheless a challenging task: Which features, EEG channel locations and frequency bands are best suited for is an issue of ongoing research. In this paper we evaluate the use of state of the art feature extraction, feature selection and classification algorithms for EEG emotion classification using data from the de facto standard dataset, DEAP. Moreover, we present results that help choose methods to enhance classification performance while simultaneously reducing computational complexity. /fileadmin/papers/2016/2016-ackermann-healthcom-emorec.pdf http://ieeehealthcom2016.com/ Online IEEE 2016 IEEE 18th International Conference on e-Health Networking, Applications and Services (Healthcom) Munich, Germany 2016 IEEE 18th International Conference on e-Health Networking, Applications and Services (Healthcom) September 14-17, 2016 en 978-1-5090-3370-6 1 PascalAckermann ChristianKohlschein Jó AgilaBitsch Link KlausWehrle SabinaJeschke article 2015-cheng-piap-jmu JMIR Mhealth Uhealth 2016 7 20 4 3 e88 piap http://mhealth.jmir.org/2016/3/e88/ http://www.ncbi.nlm.nih.gov/pubmed/27439444 Online en 2291-5222 10.2196/mhealth.5284 1 Paula Glenda FerrerCheng Roann MunozRamos Jó AgilaBitsch Link Stephan MichaelJonas TimIx Portia Lynn QuetulioSee KlausWehrle inproceedings 2016-ramos-inpact-lexicon 2016 4 30 1--6 29% Acceptance rate /fileadmin/misc/2016/2016-ramos-inpact-lexicon.pdf http://inpact-psychologyconference.org/2016/conference-program/ Online Clara Pracana and Michael Wang World Institute for Advanced Research and Science

This makes early detection of depressive symptoms critical in its prevention and management. This paper presents and discusses the development of Psychologist in a Pocket (PiaP), a mental mHealth application for Android which screens and monitors for these symptoms, and–given the explicit permission of the user–alerts a trusted contact such as the mental health professional or a close friend, if it detects symptoms. All text inputted electronically–such as short message services, emails, social network posts–is analyzed based on keywords related to depression based on DSM-5 and ICD criteria as well as Beck's Cognitive Theory of Depression and the Self-Focus Model. Data evaluation and collection happen in the background, on- device, without requiring any user involvement. Currently, the application is in an early prototype phase entering initial clinical validation. fileadmin/papers/2015/2015-bitsch-phealth-piap.pdf Print Blobel, Bernd and Lindén, Maria and Ahmed, Mobyen Uddin IOS Press

While most of the current techniques are limited to research clinics and require excessive set-up, new consumer EEG devices connected to standard, off-the-shelf mobile devices allow us to lift these limitations. This allows neuropsychological assessment and research in mobile settings, possibly even in remote areas with limited accessibility and infrastructure, thus bringing the equip- ment to the patient, instead of bringing the patient to the equipment. We are developing an Android based mobile framework to perform EEG studies. By connecting a mobile consumer EEG headset directly to an unmodified mobile device, presenting auditory and visual stimuli, as well as user interaction, we create a self-contained experimental plat- form. We complement this platform by a toolkit for immediate evalua- tion of the recorded data directly on the device, even without internet connectivity. Initial results from the replication of two Event Related Potentials studies indicate the feasibility of the approach. fileadmin/papers/2015/2015-bitsch-phealth-brain.pdf Print Blobel, Bernd and Lindén, Maria and Ahmed, Mobyen Uddin IOS Press

By means of rotation matrices related to inertial navigation methods, the output values of a three-dimensional accelerometer or a two-dimensional inclinometer can be transformed and processed into the azimuth and dip angle of the monitored target. With the rapid growth in development and cost reduction of Micro Electro Mechanical Systems (MEMS) and Wireless Sensor Network (WSN) in recent years, the engineers are able to carry out real-time wireless geotechnical monitoring during construction. In this paper, we set up a one-day measurement implemented by a self- developed wireless MEMS monitoring system on the surface in the construction site of South Hongmei Road super high way tunnel in Shanghai, by making use of rotation matrices in specific ways, the raw data are processed to expressions of three-dimensional normal vectors that represent the change of the ground. After unifying the vectors in the same coordinate system, we conduct a brief ground settlement analysis by means of an evaluation of the dip angles in the cross section and the azimuths of the sensor nodes. http://www.irsm.cas.cz/index_en.php?page=acta_detail_doi&id=96 Online Institute of Rock Structure and Mechanics of the ASCR, v.v.i.

Lifting these limitations brought about by this artificial set-up would allow us to perform neuropsychological assessments and research in mobile settings or at locations easier accessible to patients, possibly even in remote, hard to access areas. We developed a tablet based mobile framework to present auditory and visual stimuli, capture wireless commercial EEG and screen interaction data, and analyze the recorded data for immediate evaluation, as well as share the data over internet or local opportunistic links. To demonstrate the feasibility of our approach, we successfully replicated the experimental set-up and evaluation pipeline of two existing EEG studies on event-related potentials. This work therefore lays the foundation to further truly mobile brain research and health-care applications. fileadmin/papers/2014/2014-bitsch-extremcom-mobile-eeg-demo.pdf Online Hui, Pan and Lindgren, Anders ACM Proceedings of the 6th Extreme Conference on Communication Galapagos Islands, Ecuador 6th Extreme Conference on Communication August 11-15, 2014 en 978-1-4503-2929-3 1 Jó AgilaBitsch Link RoannRamos DavidOrlea KlausWehrle inproceedings 2014-bitsch-extremecom-liquid-democracy 2014 8 14 1--4 Work in Progress Paper fileadmin/papers/2014/2014-bitsch-extremecom-liquid-democracy.pdf Online Hui, Pan and Lindgren, Anders ACM Proceedings of the 6th Extreme Conference on Communication Galapagos Islands, Ecuador 6th Extreme Conference on Communication August 11-15, 2014 en 978-1-4503-2929-3 1 Jó AgilaBitsch Link AngelTchorbadjiiski KlausWehrle inproceedings 2013-wintech-bosling-models 2013 9 30 65--72 https://www.comsys.rwth-aachen.de/fileadmin/papers/2013/2013-bosling-wintech-fingerprint.pdf Online ACM Proceedings of the 8th ACM International Workshop on Wireless Network Testbeds, Experimental Evaluation and Characterization (WiNTECH 2013), Miami, USA Miami, USA 8th ACM International Workshop on Wireless Network Testbeds, Experimental Evaluation and Characterization (WiNTECH 2013) 30 September 2013 en 10.1145/2505469.2505477 1 MarcelBosling MatteoCeriotti TorstenZimmermann Jó AgilaBitsch Link KlausWehrle inproceedings 2013-smith-extremecom-demo 2013 8 24 1--2 won "coolest demo award" fileadmin/papers/2013/2013-smith-extremecom-opportunistic-deployment-support.pdf Online Hui, Pan and Lindgren, Anders ACM Proceedings of the 5th Extreme Conference on Communication Thorsmork, Iceland 5th Extreme Conference on Communication August 24-30, 2013 en 978-1-4503-2171-6 1 PaulSmith Jó AgilaBitsch Link KlausWehrle inproceedings 2013-bitsch-extremecom-oneway 2013 8 24 1--6 fileadmin/papers/2013/2013-bitsch-extremecom-oneway.pdf Online Hui, Pan and Lindgren, Anders ACM Proceedings of the 5th Extreme Conference on Communication Thorsmork, Iceland 5th Extreme Conference on Communication August 24-30, 2013 en 978-1-4503-2171-6 1 Jó AgilaBitsch Link AlaaAlhamoud KlausWehrle article 2013-fernandez-ceriotti-bitsch-and-then-the-weekend-jsan Journal of Sensor and Actuator Networks 2013 3 11 2 1 156--171 Wireless Sensor Networks (WSNs) are versatile monitoring systems that can provide a large amount of real-time data in scenarios where wired infrastructures are inapplicable or expensive. This technology is expected to be handled by domain experts, who perceive a WSN as a (promised to be) easy to deploy black box. This work presents the deployment experience of a WSN, as conducted by domain experts, in a ground improvement area. Building upon off-the-shelf solutions, a fuel cell powered gateway and 21 sensor devices measuring acceleration, inclination, temperature and barometric pressure were installed to monitor ground subsidence. We report about how poor GSM service, malfunctioning hardware, unknown communication patterns and obscure proprietary software required in-field ad-hoc solutions.

The search for a killer application is still ongoing. Our architecture enables the community to quickly proto- type new services and test them in the real world, outside of simulators. Common tasks such as data transportation through the network is handled by the framework but can still be in uenced by the service, if required. A robust plu- gin architecture allows to deploy new applications and rout- ing schemes without aecting stable-running services on the same network, even if the source of the new plugin is un- trusted.

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. fileadmin/papers/2011/2011-GlobeCom-bitsch-geoDTN.pdf Online

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.

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.

RatMote has been developed for project RatPack, which aims at creating a new method for behavioral research on rats in their natural environment using wireless sensor nodes. Recent development in microcontroller architecture allowed us to design a sensor node which calculates up to 22 times more operations per mAh than the widely used TelosB node. This significant performance and efficiency increase allows us to perform computationally demanding algorithms inside the node, needed for vocalization analysis, localization, and mapping.

We explore the model of similarity and betweenness over weighted graphs, and present a simulation on realistic traces from previous experiments, comparing our approach to the original SimBet, Epidemic Routing and Prophet.

Current link estimators focus mainly on identifying long-term stable links for routing, leaving out a potentiality large set of intermediate links offering significant routing progress. Fine-grained analysis of link qualities reveals that such intermediate links are bursty, i.e., stable in the short term. In this paper, we use short-term estimation of wireless links to accurately identify short-term stable periods of transmission on bursty links. Our approach allows a routing protocol to forward packets over bursty links if they offer better routing progress than long-term stable links. We integrate a Short Term Link Estimator and its associated routing strategy with a standard routing protocol for sensor networks. Our evaluation reveals an average of 22% reduction in the overall transmissions when routing over long-range bursty links. Our approach is not tied to any special routing protocol and integrates seamlessly with existing routing protocols and link estimators. wld fileadmin/papers/2009/2009-08-alizai-fgsn-bursty-routing.pdf doku.b.tu-harburg.de/volltexte/2009/581/pdf/proceedings.pdf Print Technical University Hamburg

The space and weight constraints resulting from the size of the animals have led to simple but functional approaches for vocalization classification and position estimation. For the resulting data we have developed novel, delay-tolerant routing and collection strategies. These are expected to be used in a sparse, dynamic network resulting from various rats being tagged with our nodes and running around freely - an area that will eventually be too big to be covered solely by stationary data sinks. Furthermore, the system is designed to extract information on the social interactions between animals from the routing data. It currently works in an indoor environment and we are preparing it for tests in a controlled outdoor setup.

Due to their distributed and faulty nature, severe resource constraints, unobservable interactions, and limited human interaction, sensor networks, make monitoring and debugging of applications strenuous and more challenging. In this paper we present KleeNet - a Klee based platform independent bug hunting tool for sensor network applications before deployment - which can automatically test applications for all possible inputs, and hence, ensures memory safety for TinyOS based applications. Upon finding a bug, KleeNet generates a concrete test case with real input values identifying a specific error path in a program. Additionally, we show that KleeNet integrates well into TinyOS application development life cycle with minimum manual effort, making it easy for developers to test their applications. kleenet fileadmin/papers/2008/2008-09-Sasnauskas-FGSN08-BugHunting.pdf ftp://ftp.inf.fu-berlin.de/pub/reports/tr-b-08-12.pdf Print Freie Universität Berlin, Institute of Computer Science

For this purpose we are using wireless sensor networks, monitoring various quantities that yield important information to complement current knowledge on the behavioral repertoire of rats. So far, on the sensing and processing side we have developed innovative, minimalist approaches pointing in two directions: vocalization analysis and movement tracking. On the data collection and routing side we have adapted to the known burrowing habits of rats by developing new methods for synchronization and data aggregation under the paradigm of sporadic connectivity in a sparse, dynamic network.

To study this behaviour, we will resort to the use of wireless sensor networks, monitoring various quantities that yield important information to complement current knowledge on the behavioural repertoire of rats. The challenges we face include data acquisition and processing on the one hand, as rat-borne sensor nodes will need to be small enough not to interfere with the rats' own activities, thus limiting the available memory and processing capabilities. Additionally, rats spend a significant amount of time underground, making data transmission and routing a very interesting challenge, for which we are currently developing novel strategies.
