Abstract
Unmanned aerial vehicle (UAV)-assisted visible light communication (VLC) constitutes a promising approach for providing illumination and communication simultaneously. In this paper, we consider the problem of joint UAV deployment, cell association, and power allocation, to meet the illumination and data rate demands of a set of users in a geographical area. Towards this goal, we develop <monospace xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">SOUVLC</monospace> , a multi-objective <monospace xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</monospace> equentially <monospace xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">o</monospace> ptimized <monospace xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">U</monospace> AV-assisted <monospace xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">VLC</monospace> framework that aims at minimizing the required number of UAVs <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">first</i> and minimizing the total transmitted power <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">second</i> . <monospace xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">SOUVLC</monospace> mitigates inter-cell interference and accounts for illumination interference. We derive a mixed-integer linear formulation of <monospace xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">SOUVLC</monospace> , numerically evaluate it under different user demands and distributions, and demonstrate its superiority over several benchmarks.
