Smart color channel allocation for visible light communication cell ID

In wireless communication network, multi-channel communication technology is a promising solution for throughput performance enhancement and collision avoidance. Similarly with visible light communication, multi-channel approach will show more advances due to the limitation of color channel and co-channel interference at the photo detector. In this research, we proposed a new color channel allocation for visible light communication Cell ID based on IEEE 802.15.7 specification. The proposed scheme is based on feedback channel information, channel priority and cognitive technique. We hope that with the flexibility, efficiency, and reliable scheduling of cognitive issue, it proves to a promising technology for future wireless network generally and especially visible light communication. The numerical results and experimental implementation show the enhancement of signal-to-noise ratio, blocking probability, and CCA time.
