Purpose Vertical handoff mechanism (VHO) becomes very popular because of the
improvements in the mobility models. These developments are less to certain circumstances …

Handover (HO), as a key aspect of mobility management, plays an important role in
improving network quality and mobility performance in mobile networks. Especially, in 5G …

Future wireless networks will consist of multiple heterogeneous access technologies such
as UMTS, WLAN and Wi-Max. The main challenge in these networks is to provide users with …

The strongest-cell criterion has been extensively used for handover algorithms during the
last cellular-network generations. When network topologies become multi-layered, it results …

The heterogeneous distribution of user's mobility and traffic profiles in mobile networks leads
to challenges handling localized network congestions and radio links failures (RLF). Mobility …

One of the most anticipated approaches to overcoming the uncertainty of millimeter wave
(mmWave) network is the deployment of ultra-dense small-cells in future fifth generation …

With fastWith fast growing traffic, high-density small cells (SC) deployment is envisioned in
5G network under the macrocell (MC) coverage area. This will improve the capacity and the …

One of the necessities of mobile networks is uninterrupted access to wireless services,
taking into account the requirements of quality of service. With the development of the fifth …

With the advent of femtocells in cellular networks, the inter-cell handover process will
become more complex, frequent and time-sensitive. The legacy handover procedures in 3G …

In this paper, we propose a distributed mobility robustness optimization algorithm to
minimize handover failures due to radio link failures by adjusting time-to-trigger and offset …
