Visible light communication (VLC) has emerged as 1 a potential wireless connectivity solution for infrastructure-to-2 vehicle networks where street lights can be configured to serve 3 as access points. In this letter, we propose dynamic soft handover 4 algorithm based on coordinated multipoint (CoMP) transmission. 5 The proposed algorithm takes the rate of change in the received 6 power as an input and accordingly revises the handover margin 7 and time-to-trigger value without explicit information of the vehi-8 cle velocity. Our simulation results demonstrate that the proposed 9 algorithm outperforms conventional CoMP and hard handover 10 and maintains a stable signal quality regardless of vehicle velocity.
