Optimization of Bluetooth Frame Format for Efficient Performance

This article studies improving of coloured JPEG image transmission over mobile wireless personal area network through the Bluetooth networks. This article uses many types of enhanced data rate and asynchronous connectionless packets. It presents a proposed chaotic interleaving technique for improving a transmission of coloured images over burst error environment through merging it with error control scheme. The computational complexity of the used different error control schemes is considered. A comparison study between different scenarios of the image transmission is held in to choose an effective technique. The simulation experiments are carried over the correlated fading channel using the widely accepted Jakes' model. Our experiments reveal that the proposed chaotic interleaving technique enhances quality of the received coloured image. Our simulation results show that the convolutional codes with longer constraint length are effective if its complexity is ignored. It reveals also that the standard error control scheme of old Bluetooth versions is ineffective in the case of coloured image transmission over mobile Bluetooth network. Finally, the proposed scenarios of the standard error control scheme with the chaotic interleaver perform better than the convolutional codes with reducing the complexity.

Channel Quality Driven Data Rate (CQDDR) play main role in the throughput factor over IEEE 802.15.1 Bluetooth network. CQDDR is employed to selects the packet size by Received Signal Strength Indicator (RSSI) over Bluetooth network according to channel conditions. This paper tries to improve the throughput over Bluetooth system in classic and Enhanced Data Rate (EDR) packets. The paper studies the adaptive Bluetooth packet format according to CQDDR decision which determines when it can extend the payload (PL) of transmitted packets. This paper proposes transmitting uncoded Access Code (AC) and the header (HD) as optional packets type. Many of proposed packets format are studied in additive White Gaussian Noise (AWGN) and fading channels. Our simulation experiments reveal the capability of extension the PL length by 8 bytes for classic BT and 16 bytes for EDR BT. Also, the experiments reveal ineffectiveness of error control schemes of AC and HD in the case of uncoded packets (DH1). That means in good channel condition the redundant bits can be added to exceed the length of the PL.
