TIO: A VLC-enabled hybrid data center network architecture [PDF]

Tsinghua Science and Technology, 2019
To satisfy the ever-increasing bandwidth demand of modern data centers, researchers have proposed hybrid Data Center Networks (DCNs), which employ high-bandwidth Optical Circuit Switches (OCSs) to compensate for Electrical Packet Switches (EPS). Existing designs, such as Helios and c-Through, mainly focus on reconfiguring optical devices to meet the ...

A Flexible Transport Layer Protocol Architecture for Handover in a Vehicular VLC Network [PDF]

2020 12th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP), 2020
Recent research works have focused on the feasibility of using the multipath-transmission control protocol (MPTCP) in order to optimize network throughput and latency. In this work, we propose a novel architecture using MPTCP for a vehicular visible light communications (VLC) network to improve the performance in terms of network outage duration and ...

Novel First-one detector architecture applied in VLC

IEICE Electronics Express, 2009
The variable length coding (VLC) has gained greater attention due to its wide application in the international standard, H.264/AVC and Chinese standard, AVS. A First-one detector is an indispensable module of VLC, such as CAVLC and Exp-Golomb coding. In this paper, a novel First-one implementation architecture is proposed, which can locate the First ...

Digitally Controlled Micro-LED Array for Linear Visible Light Communication Systems

IEEE Photonics Journal, 2015
In a visible light communications (VLC) system, the frequency response of the light-emitting diode (LED) limits the signal bandwidth and, thus, becomes the bottleneck of the transmission data rate.
