Cell sizes of the Fifth Generation (5G) of mobile networks grow inexorably smaller because
of the massive Multiple-Input Multiple-Output (MIMO) and millimeter wave communication …

In the 5G era, user equipment connected to 5G base stations can obtain better
communication services. However, due to the limited coverage of base stations, the …

To ensure a seamless mobility of users in the scenario with flying base stations (FlyBSs) and
static ground base stations (GBSs), an efficient handover mechanism is required. In this …

Nowadays, the rapid increase in the development of the wireless communication, the
Evolved Universal Terrestrial Radio Access (E-UTRA) of the Long Term Evolution (LTE) is …

A large number of small cells in the next-generation mobile networks is expected to be
deployed to satisfy 5G requirements. Mobility management is one of the important issues …

Increasing the deployment density of small base stations (SBS) is a key method designed to
satisfy high data traffic in 5th generation mobile network (5G). However, a large number of …

We propose a cell selection scheme based on the moving direction and velocity of a user
that reduces the number of handovers resulting from the 5G multi-layered Radio Access …

The integration of sub-6 GHz and millimeter wave (mmWave) bands has a great potential to
enable both reliable coverage and high data rate in future vehicular networks. Nevertheless …

High mobility travelling trains and drones connected via ultra-dense mobile networks may
lead to frequent handovers (HOs). As a consequence, this could arise the mobility problems …

Although millimeter wave (mmWave) is a promising technology in 5G communication, its
severe path attenuation and susceptibility to line-of-sight (LOS) blockage result in much …
