摘要：Recently research works on Underwater Wireless Optical Communication (UOWC) have been emerging but most researchers mainly focus on the physical layer issues. To improve channel utilization and realize high-capacity Underwater Wireless Optical Networks (UOWNs), this paper addresses the Maximum Link Scheduling (MLS) problem which aims to maximize the number of links scheduled in one time-slot. To solve this problem, firstly we establish an interference model for UOWNs via adopting the viewpoint of the physical interference model. Then we propose an algorithm to solve MLS problem and give the mathematical proof of correctness. Besides we conduct real experiments to verify our model and derive an empirical model. Finally, we conduct comparative simulations under two models and results show that the algorithm significantly improves channel utilization. Also we study the impact of parameters on the performance. Results show that a larger FOV (Field of View) of transmitters leads to worse performance and larger attenuation coefficients bring better performance.
