Abstract—IEEE 802.15.7 is introduced to standardize the visible light communication system for connecting devices via visible light spectrum. A slotted CSMA/CA MAC protocol defined in the standard to coordinate channel access for numbers of the optical wireless devices. In this paper, we proposed a Discrete Time Markov Chain (DTMC) model for modeling the behavior of the Contention Access Period (CAP) of the IEEE 802.15.7 to acquire valuable insightsand inner workings of the protocol. The through performance of the Contention Access Period (CAP) of the IEEE 802.15.7 is analyzed. ns-2 simulations are used to verify the accuracy of the proposed model. The results between the proposed model and ns-2 simulation are closely matched. Thus, verify the accuracy of the proposed model.

Index Terms—Discrete time Markov chain, IEEE 802.15.7, medium access layer, visible light communication.
