Mobility management has always been a challenging and important issue for the next‐
generation all‐IP mobile networks. Seamless mobility is one of the requirements to provide …

The pervasive use of smartphones in daily life and the advanced expansion of cellular
networks (LTE) has strongly increased the amount of mobile data traffic and has established …

Energy efficiency in cellular and wireless networks is among the major concerns of the
industry. This is of particular significance for some rural areas and for developing countries …

In 5G, the required target for interruption time during a handover (HO) is 0 ms. However,
when a handover failure (HOF) occurs, the interruption time increases significantly to more …

Network densification is foreseen as a potential solution to fulfill the 5G spectral efficiency
requirements. The spectral efficiency is improved by shrinking base stations'(BSs) footprints …

To coordinate the various access technologies in the 4G communication system, intelligent
vertical handoff algorithms are required. This paper mainly deals with a novel vertical …

Traditional multi-criteria decision making (MCDM) algorithms are used in the handover of
user equipment (UE) in an Ultra Dense Network (UDN). UDN refers to the increased density …

Densely-deployed heterogeneous networks (HetNets) with large number of small cell base
stations (SBSs) will constitute one of the main pillars of emerging 5G wireless systems …

A traditional 4G handover algorithm that performs well in a macro-cell-only network could
not be employed in the 5G network with the random distribution of small base stations due to …

First, the key technologies of 5G heterogeneous wireless networks are introduced. Based on
the 5G heterogeneous network fusion architecture, heterogeneous network technologies are …
