Abstract-- This paper proposes the use of an Error-Resilient Entropy Coding (EREC) scheme for the transmission of JPEG images across a Bluetooth wireless network. Bluetooth, being an ad-hoc networking standard, can be used in multiple environments, often under difficult conditions, leading to limited bandwidth and significant Bit Error Rates (BER). Compression and transmission provisions, that avoid catastrophic failure caused by lost, delayed, or errant packets, are crucial. This paper evaluates the transmission of JPEG images through a high BER channel with varying levels of Forward Error Correction (FEC). The EREC is presented as a method for modifying the JPEG compressed images to give increased error resilience while still maintaining a high compression ratio.
