        abstract = {Visible Light Communications (VLC) is
considered as an emerging technology for indoor wireless
communications to achieve high-speed and secure
data transmission. Instead of using radio frequency (RF)
spectrum, VLC uses the visible light spectrum to perform
lighting and communications functions simultaneously.
Multiple access points VLC (multi-AP VLC) networks use
ceiling access point (ceiling-AP) and desk access point
(desk-AP) to provide both uniform and spot lighting in
order to achieve full coverage and high spectral efficiency.
Because mobile user equipment (UE) require
seamless connectivity when moving, fast link handover
between VLC access points (VLC-AP) has to be supported
in the VLC networks. In this paper, we present a coordinated
multi-channel transmission method (CMcT)
used to improve quality of service (QoS) of cell-edge UEs
and propose a novel proactive link handover scheme
deploying the CMcT method for multi-AP VLC networks.
Performance results obtained by computer simulation
show that the proactive link handover scheme deploying
the CMcT method can significantly improve user
throughput and packet delay comparing with those of
other link handover schemes.}
