Summer Term 2011

Tutor: Marcus Handte 

Nowadays, most devices are equipped with differnt types of networking technology and a broad spectrum of sensors. Examples include gyroscopes, accelerometers, cameras, and microphones. To provide better task support, future applications will have to use the sensors of multiple devices to determine the state of their environment in an automated fashion. This requires novel software systems and signal processing algorithms to derive high-level context information from low-level sensor readings.

The seminar topics will cover a selection of systems and algorithms to recognize different types of context. Furthermore, they cover supportive architectures and protocols to recognize context in a distributed manner. Thereby, the seminar focuses on light-weight approaches that can be implemented on resource-poor devices. Participants will be able to select their topic of choice from the set of available topics.

Participants will have to do a literature research and they will have to create a written high quality report. Furthermore, they will have to give an oral presentation of their topics. Note that it is not possible to combine this seminar with the context recognition with mobile devices project at the master/diploma level.

This seminar is suitable for students at the bachelor or master/diploma level.  However, the requirements and grading scheme will be different depending on the level. Furthermore, depending on the number and type of participants, this seminar might be given in English and German. Please also note that the maximum number of participants is limited. If you want to participate in the seminar, please send an email to marcus.handte@uni-due.de.

The kickoff meeting for this seminar will take place on Thursday, 7.4.2011 between 13.00h and 14.30h  in BC504. Participation in this meeting is mandatory.

More and more mobile devices are equipped with a broad variety of sensors such as gyroscopes, accelerometers, video cameras, and microphones. To provide better task support, future applications will have to use these sensors to determine the state of their environment unobtrusively. As a simple example consider smart phones that are deactivating the touch screen when they detect that the user is holding them close to his ear.

In more complicated scenarios, this requires applications to “make sense” of the multitude of inputs received at any point in time. To simplify this task, the participants will develop a software system that is able to automatically categorize different situations. This system will be developed for and tested on Android-based mobile phones which will be given out to the participants. Due to the use of Android as operating system, participants should be able to program in Java.

This course may be held in German and English depending on the number and type of participants. The project is suitable for students at the bachelor and the master/diploma level. However, the course contents and the requirements are different depending on the level. As a consequence, it is not possible to create mixed teams.If you are not sure whether you fulfill the requirements or if you want to participate in the project, please send an email to marcus.handte@uni-due.de.

In dieser Vorlesung werden grundlegende Programmiertechniken in einer objektorientierten, modernen Programmiersprache (Java) besprochen.
Inhalte im Einzelnen:
– Einführung und grundlegende Struktur von Programmen
– Lexikalische Elemente, Datentypen und Variablen, Ausdrücke und Anweisungen
– Objektorientierte Programmierung: Klassen, Methoden, Vererbung, Interfaces, Abstrakte
Klassen
– Standard und Utilityklassen
– Generische Datentypen – Anwendung von Standardtypen
– Ausnahmebehandlung
– Ein- und Ausgabe mittels Streams
– Graphische Oberflächen – Einführung
– Ereignisbehandlung
– Anwendung der JSDK Utility Programme (Javadoc etc.)

Die Übungen sollen die Studenten anregen die in der Vorlesung gelernten theoretischen Konzepte praktisch anzuwenden. Dabei werden grundlegende Programmierkenntnisse erworben und die Studenten in die Lage versetzt einfache Programmieraufgaben selbstständig zu bearbeiten. Zusätzlich zu den Übungen werden Tutorien angeboten, welche Studenten mit besonderem Lernbedarf weiter unterstützen und die Inhalte der Vorlesung frühzeitig wiederholen.

Tutor: Chia-Yen Shih

The covered topics include: routing, localization, sensing coverage and communication connectivity, multi-channel communication, sensor networks simulation, modeling techniques on radio models, mobility models and sensing modalities, camera sensor networks.

This seminar is offered as the bachelor seminar. The student needs to select one of above topics and to perform in-depth research study on the chosen topic. By the end of the semester, the student is required to turn in a well-written report and to prepare an oral presentation to demonstrate the result of the study.

Please contact Chia-Yen Shih, chia-yen.shih@uni-due.de, or Umer Iqbal, umer.iqbal@uni-due.de, if you are interested in participating the seminar.

The kickoff meeting for this project will take place on Wednesday, 6.4.2011 between 16.00h and 17.30h  in BC504. Participation in this meeting is mandatory.

Wireless Sensor Networks (WSNs) have been widely deployed in many application domains including environmental monitoring, surveillance, healthcare, automation control and more. A typical WSN consists of a set of low-powered and inexpensive embedded sensor devices with specific sensing modalities and with computation as well as communication capabilities. These devices collaborate with each other by exchanging data through energy-efficient, short-range radio. The application provides its services by manipulating the sensory data collected by the deployed WSN.

In this project, you will learn how to develop an integrated application providing services by making use of a WSN. The topics that will be covered include:

• Wireless sensor system programming
• Sensory data collection
• Data delivery and communication through IEEE 802.15.4/ZigBee networks
• Interfacing between the user and the deployed WSN

The kickoff meeting for this project will take place on Wednesday, 6.4.2011 between 16.00h and 17.30h  in BC504. Participation in this meeting is mandatory.
