Course description

In this semester, some of our offered projects are supported by Microsoft's Hawaii project. By choosing one of the projects marked by Hawaii, you are eligible to participate in the [1]. (500 US dollars will be awarded to the most competent team within our university.)

We have some project(s) demo here for previous semesters.

Prerequisites

You are highly recommended to have attended the following course(s) prior to this one:

• Computer Networks (previously "Telematik")

Organization

Informational meeting

At the beginning of this semester (see #Schedule), there is an informational meeting.

Student Projects Demos

Content-centric Notification System (CNS)

A scalable, secure and timely notification system is always a necessary in daily communication. It is especially important in a disaster scenario. E.g., the government will notify the citizens about the status of the recovery, rescue and supply. The victims also need to notify their relatives (and whoever cares about them) their current status. They can also call for help (from ambulance service or any responsible service provided by the government) via such notification systems.

But the authorization is a big concern in such extreme scenarios. Authorization on a person-by-person basis is obviously not (energy, computation, and networkload) efficient. In such a system, we propose a new authorization system. A person create groups and use his own features (e.g., family name, cellphone number, eye color, etc.) as the challenge question for the group. In another word, he assumes that everyone who wants to join the group should have the knowledge of that information. Via such mechanism, a requester of a group can get authorization from other members of the group or even the network cache, thus save the cost on the group owner.

Another key feature of the project is the use of the Content-Centric Network (CCN). The new network architecture provides better support for a (topic-based) pub/sub system than the existing IP-based solutions. The demo system leverages the 6 machines in the network-lab running as CCN routers and hooks up with the HTTP translator on the edge of the network.

Topics

The following list of topics is constantly being expanded. If there is no topic that you like at the moment, please check back regularly for the most recent updates. You can also get in touch with us directly and we will try to find a topic that interests you. Also feel free to suggest your own topic(s) to the course advisors and we will accept it if the topic satisfies the requirements of this course.

Topic	Topic advisor	Initial readings	Description	Student
Large scale signal analysis	Xu ren, Mayutan Arumaithurai		Brain computer interface (BCI) lab at the Department of Neurorehabilitation Engineering focuses on decoding motor related information at the cortical level, using signals such as Electroencephalography (EEG), for the purpose of rehabilitation. In our lab, we seek to extract motor intentions (imagination or attempts) from EEG in real time, with which we use to trigger external devices (electric stimulator or robotic device) within a short latency. Currently, we are particularly interested in a special EEG signal modality called movement related cortical potential (MRCP) for the purpose of motion intention extraction. We are also working on advanced algorithms to extracting pathological signatures from EEG and EMG recordings. These signatures will also allow applying appropriate interventions.
Implementation and evaluation of 112 (emergency services) protocols	Mayutan Arumaithurai	ECRIT WG	Though, the Internet and communication means have advanced, Emergency calls (i.e. 112) can only be performed by traditional phone calls. Emergency service providers cannot handle VoIP, text and video messages. Handling such messages will allow emergency service providers to scale and thereby handle large scale emergency. The task will consist of implementing and testing both client (preferably on a phone) and server side of standardized(or currently being standardized) emergency services protocols by the IETF ECRIT working group.
Real time analysis of large scale data	Mayutan Arumaithurai			The team will have to apply current tools (and if possible improve them) to analyse large scale data at real time.
