Efficient error correction technique improving the efficiency of image transmission over a mobile Bluetooth networks

With increasing the applications fields of low-power short range wireless communication, especially Bluetooth, the most of these applications need transmitting image. This paper proposes improving the colored JPEG image transmission over mobile Bluetooth network using Enhanced Data Rate (EDR) packets with the 2DH₃ and 2DM₃ EDR Asynchronous Connectionless (ACL) packets. It proposes using efficient error control schemes to improve a transmission of colored images over Bluetooth systems. Also, it proposes different EDR packet formats for this purpose. A comparison study between different propositions is held in the paper to choose an efficient case over mobile Bluetooth network. The simulation experiments are carried over correlated Rayleigh fading channel. Our experiments reveal that the proposed convolutional code with constraint length K=3 and 7 enhances the received colored image over a bad channel. The simulation results show that the convolutional codes are good over correlated fading channel more than the traditional Bluetooth error correction scheme for EDR Bluetooth packets. The paper shows the standard error control scheme of old Bluetooth versions is ineffective in the case of colored JPEG image transmission over the mobile Bluetooth network. The proposed schemes provide packet latency. Also, it reduced the retransmission times with the lost frames reduction at low SNR.
