QoE loss score value for service migration in context aware environment

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.
