Bringing Spectrum Sensing to the Masses by Samir Das

Place: E1.022 at 14:00

Abstract:  With the explosion of mobile data, there is a growing realization that RF spectrum must be treated as an important resource that is in limited supply. Policy makers and researchers alike are promoting various forms of spectrum sharing models to improve spectrum utilization. Just like any other resource with mismatched demand and supply, all steps towards better utilization have also increased the need for large scale spectrum monitoring. We envision a future when large-scale spectrum monitoring will form an entire ecosystem of spectrum data, spectrum analytics and perhaps enable spectrum-aware apps. We are developing an end-to-end platform called SpecSense to support this vision. SpecSense (i) crowdsources spectrum monitoring to low-cost, low-power commodity SDR/embedded platforms, and (ii) provides cloud-based spectrum database and API support for spectrum analytics. In this talk I will describe the SpecSense vision and address a set of specific analytical and systems challenges in its design and operation. 

About the speaker:

Samir R. Das is a Professor and Interim Chair of the Department of Computer Science Department at Stony Brook University, State University of New York (SUNY). His research interests are in wireless networking and mobile computing, focusing on protocols, systems and performance evaluation. In the past, he received the U.S. National Science Foundation’s CAREER award. He also co-chaired the technical program committees of premier mobile networking conferences such as ACM MobiHoc and ACM MobiCom. He also served on the editorial boards of major networking journals, including IEEE/ACM Transactions on Networking, IEEE Transactions on Mobile Computing, ACM/Springer Wireless Networks Journal and Ad Hoc Networks journal.

+++ Third (Final) Day of Hackathon "Internet of Everything (IoE)" +++

Prototypes are being finalized in the morning and the groups are preparing their final presentations and demos (pitches). Everyone is invited to join us for the great conclusion of our event. It will start at 15:30 and last approximately one hour. After that you can have a closer look at the project in a fare-like atmosphere. 

We are looking forward to welcome our jury deciding the winner:

Monika Schtausberg - Head of Departement of IT, Didactics and IT-Infrastructure at Hamburg G18 School for Vocational Training
Mirko Bass - Business Development Manager Europe, Middle East, Africa, Russia at Cisco Systems
Andreas Timm-Giel - Head of the Departement of Communication Networks and Vize President Research of TUHH


The jury decided to pick two winners. Congratulations to "Team Aqua" and "Park here!" for winning the first TUHH IoE Hackathon. Each team received a 150 EUR gift certificate and was invited to join the Cisco Hackathon finals to compete against winning teams from other hackathons.


Hope to see you all at the next TUHH IoE Hackathon. It was a great event we would love to organize regularly from now on.



+++ Second Day of Hackathon "Internet of Everything (IoE)" +++

Heavy rain has interrupted our evening barbecue yesterday. Work on the prototypes went on until after midnight.

Today has started at 9 o'clock and all groups were busy preparing for the expert checkpoint this afternoon. After putting much effort into cabling and programming the devices it is time to also build some nice cases for the prototypes. Saws, screwdrivers and paint became as important as keyboards, mouses and compilers.   

At 15:30 the experts Sarah and Leo arrived, both PhD students at TUHH. All groups presented their prototypes and received fruitful feedback. Everyone is on a good way to success and just has to finish some final programming tasks, work on their User Interfaces and improve the appearance of their models. 

We are looking forward to the final tomorrow at 15:30.

+++ First Day of Hackathon "Internet of Everything (IoE)" +++

Nineteen students are working together in four groups of four to five to tackle the Societal Challenges of the European Union Horizon 2020 Programm

  • Health, demographic change and wellbeing;
  • Food security, sustainable agriculture and forestry, marine and maritime and inland water research, and the Bioeconomy;
  • Secure, clean and efficient energy;
  • Smart, green and integrated transport;
  • Climate action, environment, resource efficiency and raw materials;
  • Europe in a changing world - inclusive, innovative and reflective societies;
  • Secure societies - protecting freedom and security of Europe and its citizens. 

The four groups work on the following projects:

  1. Team Aqua: Environmental sensors attached to maritime mammals and large fish to monitor the ocean. The device is attached non-invasive and releases automatically before running out of power
  2. Smart Home Solutions (SHS): A plug-and-play solution to retrofit existing houses to become smart and use energy according to current requirements, e.g. number of people in a room
  3. The Guardian: Novel concept for package delivery over UAVs allowing rerouting and delivering the package to another trusted recipient if the intended one is not available
  4. Park here!: A system allowing people to offer their privat parking space to others. Different from existing park space brokers sensors are used to authorize vehicles and parking of unauthorized vehicles is prevented

Colibri Kick-off in Athens, 29. - 30. September 2014

From September 29.-30., 2014, the Colibri Consortium, in which Comnets HH is a partner, had a successful Kick-off meeting at EKT (National Documentation Centre) in Athens.

Colibri is a 3-year teaching innovation project funded by European Commision within the Erasmus Program. The project involves eight higher education institutions and two small enterprises from different countries in Europe including Denmark, Germany, Greece, Latvia, Norway, Poland, Spain, and Turkey.

The overall idea of Colibri is to implement new and innovative teaching methods through a joint learning activity, and to establish a “Living Lab” of students from different  study directions, universities, and countries/cultures. It promotes the take-up of innovative practices in education by supporting personalised learning approaches, collaborative learning, by making use of ICT and Open Educational Resources, and by exploring the use of blended and virtual mobility.

From summer semester 2015, Collibri will offer an ICT-focused course, in which students from the partner universities have an opportunity to learn various ICT-related subjects in virtual classes and to meet physically twice to carry out an industrial project.

Each year, four master students from each partner university will be selected for the course. Further details about the project and the student selection process will be available soon.
