Mobile edge computing (MEC) provides a promising approach to significantly reduce
network operational cost and improve quality of service (QoS) of mobile users by pushing
computation resources to the network edges, and enables a scalable Internet of Things (IoT)
architecture for time-sensitive applications (e-healthcare, real-time monitoring, and so on.).
However, the mobility of mobile users and the limited coverage of edge servers can result in
significant network performance degradation, dramatic drop in QoS, and even interruption of …
