Due to paper length limitations, this paper only focus on the first set of experiments.
From the second set of experiments only the conclusions of this research is reported.
The results show that, without a mobility prediction system (to predict movements of users), service continuity will be difficult to be supported since the RTT of Interest/Data packet can take longer than the threshold (>200 ms) when VM and
content migration occurs.
For instance, if the size of migrated VM is 128 MB, seamless service continuity can be supported only if the VM can be migrated and ready in the target data
centre at least 22 seconds before the handover is triggered.
Therefore, solutions such as mobility prediction are needed to predict the movement of users and determine when the VM migration should be triggered in advance.
