802.15.13 standardındaki optik ağların analizi ve optimizasyonu

In recent years, commercialization of visible light communication networks have started. As a result, there are multiple groups working for their standardization. In this work, we focus on one of them, which is IEEE 802.15 Task Group 13 and their 802.15.13 Optical Wireless Personal Area Networks (OWPAN) standard draft. The network generated according to the draft is analysed for network load and an algorithm to improve network throughput is proposed. In 802.15.13 draft, the MAC protocol uses contention free and contention access periods. This paper investigates how those period lengths should be determined. Our suggested algorithm improves the performance of the network at least 5% in the case of variable network traffic up to 15 active~users.
