In this paper, we study the scalability issues of SDNized wireless networks, specifically those
relevant to mobility management. We study the improvements in handover delays: i) when a …

The evolving network technologies aim at meeting the envisioned communication demands
of future smart cities and applications. Although software-defined networking (SDN) enables …

In this paper we discuss the evolution of mobility management mechanisms in mobile
networks. We emphasize problems with current mobility management approaches in case of …

Centralized mobility management (CMM) is widely used in current long-term evolution (LTE)
networks. The rapidly-growing number of mobile subscribers has led to the creation of a …

5G, as the next generation telecommunications architecture that aims to tackle the explosion
of connected devices, services and access technologies, will heavily rely on Software …

A network-assisted mobility management scheme has been proposed in this work for a
Software-Defined Network (SDN). Instead of using just one controller as is the case in the …

Wi-Fi network roaming is the act of moving a wireless device from one Wi-Fi access point
(AP) to another Wi-Fi AP. In urban environments, where APs are densely deployed, users …

Software-Defined Networking (SDN) is transforming the networking ecosystem. SDN allows
network operators to easily and quickly introduce new services and flexibly adapt to their …

The emerging Software-Defined Networking (SDN) concept aims at simplifying network
management and control. SDN is envisioned as one of the core technologies for future …

In a large number of network construction, due to the use of wireless devices reflects a great
convenience, the proportion of wireless network users is growing. Intelligent mobile terminal …
