Abstract

In this paper, we propose a mechanism to support priority MAC based on multi-parameter for IEEE 802.15.7 visible light communication (VLC). By using three parameters such as number of backoff times (NB), backoff exponent (BE) and contention window (CW), we provide priority for multilevel differentiated service. We consider beacon-enabled visible light communication personal area network (VPAN) mode with slotted version for random access algorithm in this paper. Based on a discrete-time Markov chain, we analyze the performance of propose mechanism. By building a Markov chain model for multi-parameter, this paper presents the throughput for VLC system. Through numerical results, we observe the effects of multi-parameter to support priority MAC.
