Abstract
In this paper, based on the analysis of indoor VLC optical link characteristics and the aid of graph theory the idea of interference-avoid is introduced to remove the signal interference from adjacent optical access points and thus the network throughput is optimized. The interference-avoidance is achieved on the network management layer by a central resource schedule scheme following our adjusted proportional fairness schedule (PFS) rule. In this schedule rule a new priority model is proposed to take into account the delay and fairness while optimizing the throughput. Simulations proved the proposed scheduling scheme can improve the throughput for small-to-moderate scale networks compared to the present work without compromise the fairness and latency performances.
