| Summary |
Image sensor communication (ISC), which
is derived from visible light communication (VLC), is a
novel form of wireless communication that uses an image
sensor as a receiver. ISC is an attractive solution for
outdoor mobile environments and is particularly wellsuited
to intelligent transport systems (ITS). The purpose
of this paper is to derive the dominant components of
vehicle vibrations and road surface irregularities that
induce transmitter displacement in ITS-ICS in paved road
scenarios. Such displacements make it difficult for a ISC
receiver to select the correct pixels. We measured vehicle
vibrations during an actual driving scenario using a sixaxis
acceleration sensor installed in a smartphone. Using
the results obtained, we performed a frequency analysis of
the vehicle vibrations and determined the parameters of
vehicle vibrations based on the frequency characteristics.
This paper explains that the vehicle vibrations that affect
the communication performance can be modeled by solely
using Gaussian random processes when a high frame rate
(e.g. 1000 fps) image sensor is used as the ISC receiver. |
