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.

Design efficient an interactive system for water pollution monitoring and quality control is proposed in this paper utilizing different sensors and employing Information Communication Technology (ICT). The presented system is built based on the pH and temperature water parameters. The system consists of sensors, Arduino controller and designed Graphical User Interface (GUI).  GUI is designed to display the parameters values and control option. The operator can control the parameters values through operating control systems by a set of control switches in GUI.  For example, the result of pH parameter during the monitoring = 7.06, while after operating the control system the pH parameter = 10.16. This result shows the ability of the system to monitor and control of water parameters. Different water parameters and properties are discussed in this paper also.
