         Framework of Visible Light Communications in IoT Networks
                        draft-chkim-vlc-iot-00.txt

Abstract

   The LED-based Visible Light Communication (VLC) has been proposed as
   the IEEE 802.15.7-2011 standard and regarded as a new wireless access
   medium in IoT environment. With this trend, many works have so far
   been made to improve the performance of VLC. However, how to
   effectively integrate VLC services into IoT networks has not been
   studied enough. In this document, 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.

1. Introduction

   Recently, 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 BLE and ZigBee, as well
   as the protocols to support packet delivery, such as CoAP [RFC7252],
