    Less latency with smarter WiFi

    Choppy Skype calls and films on Netflix that suddenly start buffering. Such types of latency can be extremely irritating, but will soon become a thing of the past. Toke Høiland-Jørgensen, researcher at Karlstad University, has developed a solution for smarter WiFi that may soon be in all our homes.

    “WiFi technology is used everywhere because it is cheap and simple. The quality is not always great, but performance can be improved by directing data streams in smarter ways. In this way, the queueing that results in extra latency in WiFi networks can be avoided,” says Toke Høiland-Jørgensen, who recently obtained his doctorate in Computer Science from Karlstad University.

    Awards showered on Computer Science

    Several Computer Science researchers and students have received nice awards at conferences during November. Congratulations to:

    • Nurul Momen, who received the Best Poster Award at NordSec in Oslo. The title of the poster is “User Perception Analysis for Showing Personal Data Access as Privacy Implication Factor”.

    • Dejene Boru Oljira, who received the Best Paper Award at Networks of the Future in Poznan. The paper, “MDTCP: Towards a Practical Multipath Congestion Control for Telco Cloud Datacenters”, is co-authored by Karl-Johan Grinnemo, Anna Brunström and Javid Taheri.

    Researchers met helthcare developers at this year's Research Vernissage

    “I lead the DigitalWell Research project that aims to enhance the development of digital welfare services. Meeting people from businesses and organisations at a vernissage was interesting and different,” says Stefan Alfredsson, a computer scientist from Karlstad University.

    DigitalWell Research will create an innovation environment in which small and medium-sized businesses develop digital welfare services in close cooperation with researchers and the public sector.

    Major investment in the development of digital welfare services

    DigitalWell Arena, a Värmland-based project that includes Computer Science at Karlstad University, is one of the winners of Vinnova’s Vinnväxt competition. Over 10 years, SEK 148 million will be invested in the development of digital welfare services. The aim is to make it easy for all residents to prevent illness and receive the necessary support regarding health issues.

    Through the Academy for Smart Specialisation and Vinnova, Karlstad University is granted around SEK 26 million for the initial three-year phase. The funding is shared by the Computer Science research group, the Service Research Center (CTF), Nursing, the Centre for Gender Studies (CGF) and the Grants and Innovation Office.

    “It is fantastic that we as a university can contribute to the development of welfare service through excellent research. I think this will also be positive for recruiting researchers to our research groups,” says Vice-Chancellor Johan Sterte.

    Internet of Things – what happens behind the scenes?

    Lamps that are switched on and off via an app, garbage cans that signal when it is time to be emptied and children who are tracked via watches. These are all examples of smart units gaining more ground in our everyday lives. Participants in the SNITS lunch on 6 November learned more about the Internet of Things and the technology behind it.

    The Internet of Things refers to devices that are not traditionally networked, such as watches, toys and machines. Today, new radio technology means that such devices can also be connected in order to collect and exchange data.

    Researchers contribute to using cloud services more securely

    Many businesses use cloud services to analyse high volumes of data, but this means that businesses lose control of data and that privacy cannot be safeguarded. A European innovation project involving researchers from Karlstad University will create a new platform for enhancing privacy in data analysis. The aim is to increase the security of businesses and safeguard individuals’ privacy when using cloud services for data analysis.

    PAPAYA, the Platform for Privacy preserving data Analytics, is a European innovation project that will create a new platform for enhancing privacy in data analysis. The platform will not have direct access to the data that will be analysed, resulting in a new type of cloud service that enables completely secure analysis of sensitive data such as personal or patient data.

    There is a significant demand for secure analytic services, particularly after the introduction of the General Data Protection Regulation (GDPR), which places higher demands on safeguarding privacy.
