Multimedia issues over bluetooth (video streaming)

Abstract

In this new era wireless ad hoc networks have become a growing area of research. The arrival of Bluetooth wireless technology makes it possible to transmit real-time video/audio in mobile and permeate environments. Multimedia content has become more accessible to mobile phone devices increasing the demand for multimedia services. Streaming video to or from mobile phones over mobile phone operator networks is one option. However, current Bluetooth network is not much suitable for traditional media encoding and real-time transmission due to limited bandwidth, high degree of error rates, and the time-varying nature of the radio link. Therefore video streaming over Bluetooth poses many challenges. In our research we analyzed the performance of Bluetooth video streaming in piconet architecture. Using NS2 simulation tool with the UCBT patch for Bluetooth, the optimal data size and distance along for a piconet with 7 slaves was detected for the intermediate protocol L2CAP. Then performance was analyzed based on Wi-Fi interference and compression techniques.
