Abstract

This paper introduces VL-mac, a media access control (MAC) protocol for visible light communication (VLC)-based cognitive radio systems. VL-mac provides a full stack of access control primitives for users that operate at visible light frequencies to access the base station and for the base station to assign resources intelligently to accessing users, such that the spatial resource is maximized. Specifically, VL-mac supports users that are located in different places in space to communicate with the base station without interference even at the same frequency, saving frequency resources substantially. VL-mac also makes sure that users are running in a completely battery-free manner, which essentially makes system deployment in a wide range of scenarios possible, including office environment, street environment, and even maritime communication.
