Particulate matter (PM) has a diameter of few micrometers, which causes different illnesses. We used visible light communication (VLC) to transfer PM data to a user monitoring terminal in real-time. To reduce the time and power required for communication, we compressed the PM data. Subsequently, these compressed data were transmitted using a modulation technique called data-dependent multiple pulse position modulation (DDMPPM). We evaluate the performance of DDMPPM for multi-hop communication in VLC through practical experiments. For the same data set, DDMPPM utilizes a lesser frame to transfer PM data. Using DDMPPM, we achieved a total communication distance of 48 m.
