Abstract—This paper proposed a parallel transmission MAC protocol for an indoor hybrid wireless network consists of visible light communication (VLC) and radio frequency (RF). Combining the CSMA/CA algorithm and the concept of parallel transmission, the protocol can solve the multiple access problems for nodes in the hybrid network. This paper uses a two-dimensional Markov chain model to construct the channel reservation model and also gives the throughput theory analyzing algorithm of parallel channel. According the numerical results, the proposed mechanism improves the throughput and efficiency of the hybrid network.

Index Terms—Parallel transmission MAC, hybrid wireless network, visible light communication, markov chain
