Link adaptive protocol for V2LC

Abstract

As the Visible Light Communications (VLC) is growing up, it is not restricted anymore to the traditional indoor applications such as LiFi or positioning, but it finds new customers at outdoor vendors like underwater and vehicle applications. In this paper we looked at VLC challenges in Vehicular Communications from Medium Access Control point of view. We proposed Link Adaptive Protocol where a single handshake association and fast handover algorithms prolong VLC connectivity. Moreover, adaptive modulation has been suggested in order to increase the throughput. Simulation results show the link adaptive protocol outperforms slotted-aloha in outage probability and goodput, properly achieving a trade-off between pilot rate and protocol efficiency.
