QoE loss score value for service migration in context aware environment
Aamir Saeed, Jens Myrup Pedersen, Rasmus Løvenstein Olsen · 2014
The increasing amount of smart devices and handheld devices have widened the amount of information presence all over. The application running on one device can be distributed to a surrounding device for better functionality. A capability that might be enjoyable or frustrating for end user. This paper has identified the factors that contribute to the loss of user experience for seamless application migration in a context aware environment. These are the context information updates, transfer time and resumption time. To quantify the loss of user experience, a Quality of experience (QoE) Loss score value (representing the time that is lost in user experience during migrating process)is introduced. A high QoE loss score value indicates a higher loss of user experience and a lower QoE loss score value indicate a lower loss of user experience. A test-bed setup was implemented and different policies of migration processes in a context aware environment were evaluated.
