In vehicle-to-vehicle networks and wearable devices, tracking algorithms, as proposed in this work, allow one to reduce the time required to locate a moving source and hence the latency of these systems  ...  Moreover, data bits sent over the red and blue channels do not significantly affect detection, hence transmission occurs uninterrupted.  ...  Each band corresponds to one symbol transmitted in the case of using OOK modulation. Therefore, the use of OOK modulation can obtain higher bit rates in RS cameras than in GS cameras.  ...
