1. A system to optimize a light emitting diode (LED) power allocation framework within a room, the system comprising:
a memory storing programme instructions; and
a processor configured to execute programme instructions stored in the memory, wherein the processor comprises:
a data receiving subsystem configured to receive parameters corresponding to one or more light emitting diodes (LED), one or more visible light communication (VLC) transmitters and one or more visible light communication (VLC) receivers;
a blockage generalization subsystem configured to identify location and height of one or more detected blockages within the room from the received parameters via one or more location assistance technique,
wherein the one or more detected blockages comprises human blockage and objects,
wherein the one or more location assistance technique comprises a linear regression technique; and
an optimal power allocation subsystem configured to
compute a visible light communication (VLC) channel gain for each of the one or more light emitting diodes (LED) with reference to identified location and identified height of one or more detected blockages from the blockage generalization subsystem; and
optimize the power allocation framework to achieve maximized visible light communication (VLC) data rate based on the computed visible light communication (VLC) channel gain and one or more constraints.
