摘要 目前无线ad hoc网络发展的目标是支持多媒体数据的传输,基于ad hoc网络的视频流传输有着巨大的应用前景。但是无线传输介质的不稳定特性决定了其支持视频流传输存在较大的挑战。在分析蓝牙和802.11b技术各自优缺点的基础上,设计了基于蓝牙和802.11b无线ad hoc网络视频流传输的模拟实验架构。在不同码率和不同路径长度的模拟环境下测试了解码视频流的质量,研究、对比了二者在视频流传输中的性能。 As wireless ad hoc network architectures are now targeted to support multimedia traffic, streaming video over these technologies will give rise to interesting applications. But the variable nature of the wireless medium will not lend itself easily to supporting video streaming. After brief introduction of Bluetooth and 802. 11b, this paper designs a simulation scheme for performing video streaming over wireless ad hoc networks based on Bluetooth and 802.11b. Under different video stream rates and path lengths, the decoded video stream qualities are measured to compare and analyze the performance of Bluetooth and 802. 11b.
