Owing to an increase in mobile devices and the advent of the Internet of Things (IoT), mobile traffic has increased exponentially. Consequently, a wide range of research on handover has been conducted to provide mobile device users with stable network quality. Most research on handover uses a network-dependent method that establishes a new protocol or a method that can refine handover time; however,...
This paper proposes Mobility and HetNet-CA (Heterogeneous Network Carrier Aggregation) technology of Multi RAT(Radio Access Technology) terminal based on SDN (Software Defined Network). It improves transmission speed by using two network interfaces. These network interfaces make dual link with APs(Access Point) so that it can reduce handover latency.
