Abstract:

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 analyzed 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.

Bio: 

Yusuf Bülbül was born in Izmir. He received a B.Sc. degree in electrical engineering from the University of Gaziantep, in 2016. After graduating from university, he started to work as an Embedded Software Engineer in the industrial area. Since 2017, he has been working as an Embedded Software Engineer at Hyperion Technologies, on wireless communication technologies, free space optics (FSO) and VLC (Visible Light Communication) technologies. While working, he started his master's degree at Özyeğin University. The fact that the projects in the company he works with are parallel to the master's thesis has given him the opportunity to apply his research in this field and evaluate them from a different point of view.
