روش انتقال در ارتباطات نور مرئی بین وسیله نقلیه در حال حرکت و لامپ های متعدد LED خیابانی

When the moving vehicle is communicating with LED streetlights by visible light, the multiple LED streetlights signals will be selected or signal may be interrupted between adjacent streetlights. The method of receiving signal power (RSP) handover between the moving vehicle and multiple LED streetlights transmitters will be studied. Considering two cases, no power coverage and power overlap between adjacent streetlights. Hard RSP handover used in no power coverage model and soft RSP handover used in power overlap model. Simulation results show both RSP handover methods can protect the communication between the vehicle and LED streetlights and improve the stability of communication.
