Design, implementation, and evaluation of the audio/video distribution transport protocol (AVDTP) for high quality audio support over Bluetooth

In recent years, we have seen wide adoption of wireless local area networks frequently used as extensions to the Internet to enable ubiquitous information access anywhere, anytime. Networks such as IEEE 802.11 and Bluetooth are extensively being deployed in the local area and personal area networking environments, respectively. For seamless connectivity to the Internet, these networks are expected to transport different types of traffic often involving various media (audio, video, images). Our goal is to enable the effective transfer of high quality audio in Bluetooth Personal Area Networks (PANs). Most of the functionalities required for audio/video streaming over Bluetooth are specified by the Bluetooth Audio/Video Distribution Transport Protocol (AVDTP) specification standard. We have designed and implemented AVDTP for high-quality audio support over Bluetooth networks. We also present and discuss a performance evaluation of our AVDTP implementation.
