Communication Networks Working Group

Tutor/innen für WS 2016/17 gesucht!

Overview

 

The main research focus of the ComNets group at the University of Bremen is 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: mobility support, mobile communications, wireless communications, simulation technology, rare event simulation, teletraffic engineering. Research projects are mainly funded by national and international government institutions and direct industry collaborations.

The group consists of several post-docs as well as several 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.

News

The book "Introduction to Wireless Sensor Networks” finally published!

The book “Introduction to Wireless Sensor Networks” by Anna Förster has been published by Wiley and IEEE Press and is currently already available as an online version and very soon also as a hard-copy (July 2016). The online companion with slides, further information and links for purchasing is here. Comments are highly welcome!

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. 

Free-WLAN-Spots for refugees installed

This week, two "Freifunk"-WLAN spots were installed at the NW1 and the refugee tent behind. The bandwith supports about 30 people on low-demand services like E-Mail, Whatsapp etc. Find more information on Freifunk and their free WiFi spots on their website.
