    A new project will improve performance and privacy for 5G users

    The launch of the 5G network is approaching and the expectations are great. Both individuals and businesses are looking forward to higher speed, minimal delays, and the possibility of handling a greater number of connected devices simultaneously. But how do we make optimal use of the potential offered by 5G technology? In the project Performance and Anonymity in future 5G Networks (PAF5G), researchers at Karlstad University will study how performance can be improved through the use of multiple connections, at the same time as users’ privacy is protected.

    The 5G network will offer more flexible solutions, which means that users will be able to adapt the technology to their needs.

    High quality on our research on cloud networks

    Three scholarly articles written by researchers in Computer Science at Karlstad University have been accepted to IEEE CloudNet, a large international conference on cloud networks in Coimbra, Portugal.

    “It is unusual that a research group has three articles included in a conference at this level,”says Andreas Kassler, Professor of Computer Science. “This shows that our research is of high international standard.”

    The scholarly publications are all part of the project HITS, High Quality Networked Services in a Mobile World, the purpose of which is to contribute to the development of high quality network services for a mobile world. The research is carried out in close collaboration with partners in the industry.

    They are the top programmers in Karlstad

    Students, alumni, and representatives from local IT and technology businesses competed in the Karlstad Programming Contest on 5 October. After the contest, team Bug Repellent, consisting of Dan Wolff, Klara Jonsson, and Sigrid Österling Sicking (all of them from Altran), were pronounced winners after having solved five tasks.

    For a third time since the contest was initiated in 2012, Dan Wolff was a member of the winning team.

    New perspectives on business model innovation in water and sanitation service provision

    There are many barriers to overcome when entering the Base of the Pyramid (BoP) markets. In a new thesis, Caroline Saul has studied the roles of business models and business model innovation in providing and scaling water and sanitation services in low-income countries - she hopes that the thesis can serve as a reference for organisations looking to change or create business models for service provision in low-income countries or wish to tap into these markets.

    “785 Million people lack access to basic drinking water services, and 2.4 billion people lack access to basic sanitation services, while the waste of an additional 2 billion people enters the environment untreated. The aim of the UN's Sustainable Development Goal 6: Clean Water and Sanitation is to reduce these numbers, and significant resources are being invested worldwide in bringing these numbers down. However, doing so is not purely a technical, logistical, or humanitarian challenge.

    Bachelor’s essay presented in Cambridge

    It is unusual for a Bachelor’s essay to be of such high quality that it qualifies for presentation in an international conference. But Jonatan Langlet, a Master’s student in Computer Engineering, has proven that it is possible. On 23 September, he went to Cambridge and presented an article based on the Bachelor’s essay that he completed in the spring.

    Jonatan has developed a programmable switch, a traffic forwarder, which can analyse network traffic and identify what type of traffic it is. Is it for instance a chat message, a video conference, or someone trying to hack their way into your computer?

    “The traffic forwarder, the switch, recognises if incoming data is a video conference and can prioritise it and decrease delays. If the traffic is a hacker attack, the switch can shut down access or alert the IT department of the company,” says Jonatan Langlet.

    Javid Taheri is a new professor of Computer Science

    Javid Taheri has been promoted to a professor. Through his promotion, Computer Science acquires even more scientific competence in cloud computing.

    Javid’s field of research includes, among other things, fog computing that is the next big paradigm in the computing world. Through fog computing, cloud services can be extended to the very edge of networks; this makes it ideal for applications that require real-time interactions. Fog computing is a prerequisite for the realisation of smart cities, for instance, where digitalisation creates better living environments, saves more resources, and better addresses people’s needs.
