Distributed Interference-aware Medium Access Control for IEEE 802.15.7 Visible Light Communications
2018
Sensors and materials
Keywords: backoff exponent adaptation, CSMA/CA, IEEE 802.15.7 VLC, medium access control, VLC interferer discovery In this paper, we present a distributed interference-aware medium access control (DI-MAC) for IEEE 802.15.7 visible light communications (VLCs), which improves the spatial efficiency of VLC devices deployed in specific service areas. The DI-MAC adaptively adjusts the backoff exponent (BE) of each VLC device by considering the number of adjacent VLC devices causing the interference,
