Collaborative Networking (CoNe) group researchers got the best paper award at 2nd ACM Conference on Information-Centric Networking (ICN 2015)

 

Collaborative Networking (CoNe) group researchers got the best paper award at 2nd ACM Conference on Information-Centric Networking (ICN 2015), one of the most prestigious venues for ICN research. The article entitled Pro-Diluvian: Understanding Scoped-Flooding for Content Discovery in ICN is lead by Liang Wang - a recent PhD graduate from CoNe research group, and is the outcome of collaboration with Suzan Bayhan and Jussi Kangasharju from UH, Jörg Ott from Aalto University, Arjuna Sathiaseelan and Jon Crowcroft from Cambridge University.

ICN is a new networking paradigm with a promise to fix the mismatch between the host-centric design of the Internet and current information-centric use of the Internet.  As users are interested in getting the information rather than who provides the information, ICN proposes to address the content, let the content move around in the network based on the user requests and network's resources, and facilitate host-to-content communications natively. This approach raises the challenge of locating the content in the network, for which scoped-flooding is assumed to work efficiently.

The article comprehends the scoped-flooding for content discovery in ICNs using random graph theory and shows that most of the gains of flooding come from the sparse area at the network edge where the neighborhood growth rate is low.  This result provides a guide for how to search for content in an ICN, based on the network topology, router's location in the network as well as the requested content's availability in the network.

Discovering Computational Creativity at the University of Helsinki

Computational creativity is a relatively new field among computational sciences, but it already has an active international community of academic researchers. A part of this international community is the Discovery Research Group, run by professor Hannu Toivonen at the University of Helsinki. The group is interested especially in linguistic creativity methods, including methods for the generation of poetry, word associations, humour, and text summarisation. But the group’s efforts have also included musical composition, a human-computer co-creation study and on-going work in pictorial metaphors.

Free-Form Gestures for Mobile Authentication

In the third research result of the month we report on the recent results in gesture-based authentication of users on mobile devices. We interview Assistant Professor Teemu Roos regarding the recent accepted scientific article in the top-tier ACM MobiSys 2014 conference.

 

Strategy seminar of the Department 2014

The strategy seminar for the Department of Computer Science was arranged at the Kisakallio sports institute in Lohja on 26-27 May 2014. In addition to the strategy work, the programme included meals and coffees, sports, and sauna baths. The high winds blew frisbees and canoes into the bushes. However, the water in Lake Lohjanjärvi was warm, some 20 degrees according to the skin thermometer.
