Mobile edge computing based VM migration for QoS improvement

QoS of applications in an edge node of mobile edge computing (MEC) could degrade due to congestion of wireless access or short of mobile edge computing resource. In order to improve QoS such as TCP throughput, we propose a VM migration method, which takes a VM from congested node to another node in a mobile edge. Users can choose a far but less-congested node, instead of a near but congested node. The choice is made based on an expected TCP throughput. We analyze how much the migration can improve TCP throughput.
