Design of a handover management scheme for unmanned aerial vehicle-assisted network
Abstract
An unmanned Aerial vehicle is an autonomously flying aircraft controlled by an
individual. UAVs are currently used as aerial base stations to support the macro
and micro-ground base stations. These deployments are usually to provide coverage
and capacity. However, there are many implications that come along with the
deployment of the UAVs and the key issue is handover.
This project is aimed to design a handover management scheme that enables a
seamless handover during the mobility of the users as they move from one cell
to another in a communication network. This was achieved through modelling
a three-tier network with macro, micro, and UAV base stations, developing an
adaptive hysteresis margin algorithm that enables a smooth connection in a
UAV-assisted network the comparing the developed algorithm with the already
existing algorithm.
The results show that the performance of a network improved the algorithm by
13%. In this project, the handover performance of the networks with and without
the algorithm has been studied. the results show that the optimal triggering of
the handover depending on the hysteresis margin and signal-to-interference ratio
improves the network performance and the performance evaluation was carried
out using the number of handover success rate, spectral efficiency, and number of
successful handovers.
