Abstract
LED-based Visible Light Communication (VLC) has been proposed as the IEEE 802.15.7 standard and is regarded as a new wireless access medium in the Internet-of-Things (IoT) environment. With this trend, many works have already been made to improve the performance of VLC. However, the effectively integration of VLC services into IoT networks has not yet been sufficiently studied. In this paper, we propose a scheme for device management and data transport in IoT networks using VLC. Specifically, we discuss how to manage VLC transmitters and receivers, and to support VLC data transmission in IoT networks. The proposed scheme considers uni-directional VLC transmissions from transmitter to receivers for delivery of location-based VLC data. The backward transmission from VLC receivers will be made by using platform server and aggregation agents in the network. For validation and performance analysis, we implemented the proposed scheme with VLC-capable LED lights and open sources of oneM2M. From the experimental results for virtual museum services, we see that the VLC data packets can be exchanged within 590 ms, and the handover between VLC transmitters can be completed within 210 ms in the testbed network.
Highlights
Internet of Things (IoT) services have widely been used to improve our daily life.For example, with the help of IoT services, people can order what they need by pushing a button, or find the location where a fire has occurred by aggregating the measured values from sensors through the Internet.For realizing the IoT, there has been lots of work undertaken on wireless communication technologies such as Bluetooth Low Energy (BLE) [1] and ZigBee [2], as well as the protocols to support packet delivery, such as Constrained Application Protocol (CoAP) [3], MQ Telemetry Transport (MQTT) [4], MQTT for Sensor Networks (MQTT-SN) [5], and so on

With the help of IoT services, people can order what they need by pushing a button, or find the location where a fire has occurred by aggregating the measured values from sensors through the Internet. RF communication environments, such as huge factories, airplanes, underground facilities, and so on. Such environments need a specialized communication technology. Visible Light Communication (VLC), which is defined in the IEEE 802.15.7, is one of the communication solutions for meeting these characteristics [9]. VLC communication is carried out between transmitter and receivers using visible light. Based on this characteristic, VLC offers no interference to existing RF-based communications
