Receiver initiated ARQ scheme for LED-ID link switching

Automatic Repeat reQuest (ARQ) is widely used in wireless systems to guarantee the reliable delivery of data packets. However with the current state of Visible Light Communication, especial intensity modulation and frequency handover, the traditional ARQ shows some limitation about collision probability and new link connection. This article we propose new ARQ model for LED-ID link switching which can reduce collision effect probability, and link switching time.
