N2  - In this paper, we present a model of visible light
communication (VLC) systems which exploit light beams for
downlink transmission. A calculation method is proposed for light
beam configuration which guarantees no blind areas in the whole
VLC coverage while minimizing the number of light beams. As a
major contribution in this paper, a light beam allocation algorithm
is proposed which aims to eliminate interferences between inter
VLC Access Points (inter-APs) by using information of incoming
data queue length and co-channel interference (CCI) conditions to
decide which VLC beams are used for transmitting data to
appropriate user equipments (UEs). By deploying the proposed
algorithm, CCI can be eliminated because noise-effected regions
and noise-free regions can be separated. Performance of the novel
light beam allocation algorithm is analyzed, evaluated and then
compared with that of another light beam allocation method using
the Round-Robin algorithm. Performance results show that there
are significantly improvements in SINR, user throughput and
packet delay parameters when deploying the proposed light beam
allocation algorithm.
