许多灾难表明，移动的用户迫切需要可靠的语音通信。低功耗自组织无线网络由于其低成本和便携性，已成为一个有前途的解决方案，在紧急情况下。为了加强移动紧急人员和灾民之间的通信，我们开发了一种新型的融合广播语音流媒体系统，可以保证低功耗移动的无线网络中稳健的语音质量。该系统集成了路由和移动性感知的准入控制沿着与语音压缩调整，以确保语音流的质量。该系统使用Arduino Due微控制器和XBee 802.15.4无线电进行评估。我们的研究结果表明，我们的系统可以充分适应不断变化的网络和路由条件，提供足够的语音质量，保持一定数量的并发语音流。据我们所知，这项工作是第一个完整的系统质量感知的语音流在移动的低功耗无线网络。
Many disasters have shown the critical need for reliable voice communication for mobile users. Low power ad hoc wireless networks have become a promising solution in emergency scenarios because of their low cost and portability. In order to increase communication amongst moving emergency personnel and disaster victims, we have developed a novel convergecast voice streaming system that guarantees robust voice quality in a low power mobile wireless network. The system integrates routing and mobility-aware admission control along with voice compression adjustment to ensure the quality of voice streams. The system is evaluated using Arduino Due micro-controllers with XBee 802.15.4 radios. Our results show that our system can adequately adapt to changing network and routing conditions to deliver sufficient voice quality by maintaining a certain number of concurrent voice streams. To the best of our knowledge, this work is the first complete system for quality-aware voice streaming in mobile lower power wireless networks.
