Liebe Studentinnen und Studenten,

angesichts der Corona-Situation habe ich mich entschieden, eine virtuelle Sprechstunde anzubieten. Ich bin für Euch wie immer jeden Donnerstag zwischen 11 und 12 Uhr online erreichbar, über zoom:

Join URL: https://uni-bremen.zoom.us/j/8736209040

Bitte rechtzeitig die benötigte Software herunterladen. Beachtet auch, dass die Videokonferenz nicht automatisch alle reinlässt, sonder dass Ihr erstmal in einer Art „Warteraum“ landet. Ich werde Euch der Reihe nach in die Konferenz reinnehmen, so dass immer nur ein/e StudentIn mit mir spricht. 

Bitte beachtet die geänderten Termine für die Sprechzeiten im Juli und August, diese sind unter „Office hour Anna Förster“ angegeben! Die Uhrzeit bleibt wie immer.

Viele Grüße und bleibt alle gesund und munter!

Overview

The main research focus of the Sustainable Communication Networks group at the University of Bremen is design and performance analysis of communication networks and their protocols. This includes the implementation of prototypes as well as performance studies by mathematical analysis and simulation. The main keywords are: sensor networks, opportunistic networks, future internet. An important aspect across all reseach projects is sustainability in a two-fold aspect, i.e. how communication networks can enhance the sustainability of networking applications, and how the network itself can be designed in a sustainable way. Research projects are mainly funded by national and international government institutions.

The group consists of several post-docs as well as fully employed research assistants working on research projects and their doctoral thesis. Additionally there is a small technical and assisting team and many students working as student workers or doing their thesis.

On the Same Side ― Prof. Förster talks about the challenges of online teaching

The lecture period of summer semester 2020 was a challenge for staff and students, all lectures had to be done online. In University's online magazine up2date, Prof. Förster talks about her experience with online teaching.

Prof. Förster receives Berninghausen Award 2019

Preisverleihung an Prof. Anna Förster

Prof. Förster has received the Berninghausen Award 2019 in the category “excellent and innovative lectures”. Prof. Förster and hear team have deployed the Inverted Classroom concept in the lecture “Foundations of Computer Science” for Bachelor Students in the study program “Electrical and Information Engineering”. This teaching method shifts the task of acquiring the basic knowledge from the classroom presentation to videos and supporting learning material which the students can access anytime and anywhere through the e-learning platform. The Center for Multimedia in Teaching (ZMML) assisted the ComNets group in setting up the facilities for recording and editing the videos. The time in the classroom is used for programming assignments (“Hackathons”) which the students have to work out in teams and which are part of the grading.

The lecture includes two semesters. In the first one, the Arduino platform is used for the Hackathons which demonstrates the interaction of programming and electronic circuits which is in particular motivating for Electrical Engineering students – “software meets hardware”. The second semester introduces the powerful, but easy-to-learn Python scripting language.

More information is available here.

ComNets goes on air

Vortrag "Entscheidungsprozesse in Kommunikationsnetzen: Naturinspirierte Verfahren"

Im Rahmen der Ringvorlesung "Universelle Eigenschaften des Entscheidens" hält Frau Prof. Anna Förster am 11. Mai einen Vortrag zum Thema "Entscheidungsprozesse in Kommunikationsnetzen: Naturinspirierte Verfahren".

 

Nicht nur wir Menschen stehen ständig vor Entscheidungen, sondern auch unsere Geräte. Vor allem unsere heiss geliebten Computer stehen andauernd vor Entscheidungen, wie und wann sie welche Informationen wohin senden. Wenn ich einer Freundin eine Email schicke, gebe ich einfach eine Adresse ein. Aber wie kommt meine Email von meinem Rechner zum Rechner meiner Freundin? Findet die Email auch wirklich den kürzesten Weg dahin?

In diesem Vortrag werden wir eine Reihe von Entscheidungsprozessen für Computer & Co kennenlernen. Und zwar nicht die einfachen, trivialen Prozesse, sondern die naturinspirierten und intelligenten Prozesse. Was hat eine Ameise damit zu tun? Oder ein Vogelschwarm? Oder ein Baum? Das werden wir gemeinsam erkunden.

 

Der Vortrag findet statt am Mittwoch, 11. Mai, von 16 bis 18 Uhr in der Rotunde im Cartesium, Enrique-Schmidt-Str. 5, 28359 Bremen.

Talk: Pervasive Systems at a Glance

The Department of Sustainable Communication Networks had the pleasure to welcome Prof. Paul Havinga and Prof. Nirvana Meratnia from the University of Twente, Netherlands, for a Talk on Pervasive Systems.

Abstract: In this presentation, we will provide a short overview of core research themes and their related recent projects of the Pervasive Systems group. The common areas of research within Pervasive Systems are opportunistic sensing and wireless networking and  sensor data analytics. We will also show how major research and development challenges such as energy-efficienty, reliability, robustness, and accuracy, faced in these themes have been addressed and how the research results have been integrated through addressing practical deployment and development issues in real-world applications.

 

Prof. Paul Havinga is full professor and chair of the Pervasive Systems research group at the Computer Science department at the University of Twente in the Netherlands. He received in 2000 the 'DOW Dissertation Energy Award' for his Phd thesis. He has a broad background in various aspects of communication systems, including wireless communication, sensor networks, smart sensor systems, Cyber Physical Systems, QoS over wireless networks, reconfigurable computing, and on interconnection architectures for multiprocessor systems. The common themes in his area of research is the development of large-scale, heterogeneous, wireless, distributed systems. Research questions cover architectures, protocols, programming paradigms, algorithms, and applications. He has a significant experience as project manager in several national and international research projects on wireless sensor networks. In 2001 he initiated the first European project on wireless sensor networks EYES, and many national and international projects evolved from this. In May 2007 he received the ICT Innovation Award for the successful transfer of knowledge from university to industrial use. In June 2007 he received the "van den Kroonenberg award" for being a successful innovative entrepreneur.  

 

Dr. Nirvana Meratnia is associate professor in the Pervasive Systems Group at the University of Twente. Her research interests are in the area of Internet of Things (IoT), distributed sensor data analytics, (underwater) wireless sensor networks, and wearable/implantable communication and computing. The common themes in her area of research are energy-efficient, accurate, and reliable sensor data processing, reasoning, and interpretation. This goes hand in hand with requirements and limitations posed by the wireless communication being in air, in body, or underwater. This in turn requires a cross-layer optimization. She is and has been involved in many EU and national projects related to these themes.
