In recent years, Computational RFID tags (CRFIDs) have emerged as viable software-defined platform for academic research and experimentation. addition to EPC protocol, these perform sensing computation through power scavenging. However, existing CRFIDs are pre-programmed execute a specific firmware whereas programming tools comprising wired interface PC-based software required erase, modify or reprogram the tag. Such limitation demands an over-the-air (OTA) scheme which can wirelessly...

Optical camera communication (OCC) systems, which utilize image sensors embedded in commercial-off-the-shelf devices to detect time and spatial variations light intensity for enabling data communications, have stirred up researchers' interest. Compared a direct OCC system whose maximum rate is strongly determined by the LED source size, reflected can break that limitation since captures rays reflecting off an observation plane (e.g., wall) instead of those directly emanated from source....
