VLC network topology design for seamless communication in a urban tunnel

Abstract:

Visible Light Communications networks are usually based on isolated access points which deals individually with the handover strategy. Basically when a node is detected by an access point the network’s protocol upper layers bkp_redirect the traffic to the new access point. This strategy cannot be suitable for vehicle communications and different alternatives of handover should be developed. In this paper, a new network architecture is presented including a novel handover scheme based on distributed receivers. This system has been tested for vehicle to infrastructure applications in a tunnel scenario and results show that, in comparison with classical scheme, it demonstrates an upgrade in general performance.
