Problem Space Identification for Developing Virtual Reality Learning Environments

2021

Our study argues that the extant literature on virtual reality-based learning environments (VRLEs) currently lacks proper definitions and context descriptions for a problem space, which is fundamental for conducting design science research (DSR). Without properly conducted problem space identification, the most pivotal problems cannot be identified resulting solutions lacking validity and unreliable evaluations. This is a major challenge for the DSR in the educational field, but also for the research on VRLEs. The purpose of this paper is to introduce a novel DSR method to support rigorous problem space identification, which would allow rigorous and profound problem space analysis. The inst…

Trust management in tactical coalition software defined networks

2018

This paper reports from ongoing efforts related to trust management in tactical Software Defined Networks (SDN) when used with mobile nodes in a coalition operation. We analyze the problem space and suggests a set of security and contructional requirements, as well as an analysis on how existing technology may contribute to a solution. The proposed architecture serves as a guide for current and future experimentation on trust management and protection in SDN. The paper also reports from experimental investigations into the utility of these technology elements for the present purpose.
