Abstract
Wireless communications has become the most desirable
communication choice among users. In this thesis, we focus on two types
of Wireless Personal Area Networks (WPANs); Bluetooth and ZigBee.
The Bluetooth (IEEE 802.15.1) technology aims at allowing wireless
short-range communications between several devices. The ZigBee (IEEE
802.15.4) is a Low-Rate Wireless Personal Area Network (LR-WPAN)
designed to be simple for low-power devices and light-weight wireless
networks. The common thread between the two types of networks is the
short range coverage.
The work in this thesis comprises two main points; efficient data
framing, efficient image, and audio communication with both networks.
Different packet formats with coding and interleaving are investigated in
this thesis in Bluetooth and ZigBee networks. Block and convolutional
codes are studied in this thesis on both Bluetooth and ZigBee networks
with a complexity treatment.
Optimized packets are used in this thesis for audio and image
communication with an efficient chaotic interleaving mechanism. Audio
watermarking is exploited in this thesis as a tool to hide information
inside audio signals for transmission over Bluetooth and ZigBee
networks. The objective of this study is to increase the security of datacommunication over these types of networks, while maintaining the high
fidelity of the communicated images and signals.
