“…In this section, we evaluate the performance of the proposed light source layout optimization strategy (denoted as the distance-related scheme). The room size we consider is 5 m × 5 m and the total number of light sources is 16, as set in [12]. Therefore, the subregion partition and optimization order for each sub-region are the same as shown in Figure 2.…”

“…For the proposed optimization strategy, the FOV is set to 90°and the semi-angle at half power of the LED is set to 60°. The parameters used for the ICBA scheme are the same as those presented in [12]. We can see that the proposed optimization strategy has a larger fluctuation in the optical power distribution fluctuation compared to the ICBA scheme when L = 2.5 m. However, the range of fluctuations decreases as the distance increases.…”

“…First, we present the optimization results of the proposed optimization strategy. For comparison, the light source layout determined by the scheme proposed in [12] (denoted as immune clonal bat algorithm (ICBA)) is also presented in Figure 5. We can see that the light source layout determined by the proposed optimization strategy is different from that determined by ICBA.…”

“…The uniformity of the illumination and SNR is further improved [11]. Che and Wang proposed a hybrid immune clonal bat algorithm to optimize the layout of the light source, which enhances the fair distribution of optical power among indoor users [12]. Wang and Xu proposed an optimization scheme to improve the uniformity of the received optical power by optimizing the layout of the light source based on an artificial fish swarm algorithm [13].…”

Optimization of the light source layout is an important issue for indoor visible light communication systems, as it affects the received optical power distribution and user perception. In this paper, we propose a local optimization strategy for the light source layout that balances optimization effectiveness with optimization efficiency. First, we divide the optimization region into multiple sub-regions with different sizes and optimization priorities, where the sizes and optimization priorities of the individual sub-regions are determined based on the effect minimization principle among the sub-regions. We then calculate the pre-bias factor based on the equivalent mapping, which can compensate for the effect of the light sources in the latter optimized sub-region on the source layout optimization in the current sub-region. Finally, we search for the coordinate of a single light source for each sub-region using the variance of the squared distance between the projection of the light source on the receiving plane and the received point as a fitness function. Simulation results show that the proposed optimization strategy performs well when the vertical distance between the ceiling and the receiving plane is not less than 2.85 m.
