Two shades of IT and mobility

Published: 16 January 2015

How new technologies can be used to make digital services available anywhere and anytime. That is the topic of a new doctoral thesis at Luleå University of Technology. Traditional computers have increasingly been replaced by portable devices like smartphones and tablets, which require new solutions for mobility.

As the computer, and by extension the user, have become increasingly mobile, conditions have been created to make the actual services mobile. An important part of the delivery of a digital service is the actual computer program or application.

– During my years as a PhD student, I have studied two shades of service mobility. One is about how to make the application itself mobile, being able to move between different computers and smart devices while it is running and adapt it to the new host device, said Dan Johansson, Luleå University of Technology.

Solutions to challenges

To achieve application mobility is fraught with many challenges, such as the differences between networks and network operators, various applications are built with different programming languages ​​and to ensure that the right application is transferred to the right device at the right time, and as quickly as possible. Dan Johansson's thesis presents solutions to these issues.

– A different shade of service mobility that I looked at, are the mobile e-services, that is Internet-based services that should be available across all possible platforms at any given time. It becomes especially important if the publisher of the service is an public authority, continues Dan Johansson.

Together, application mobility and mobile e-services are two very exciting areas that can change the user's everyday live, but also the user's role in the IT community from passive consumer to creator of digital services.
