Data streaming is an emerging class of applications for sensor networks that has very high bandwidth and processing power requirements. In this paper, a new approach for speech data streaming is proposed, which is based on a distributed scheme. This scheme focuses on balancing the energy consumption among nodes in a sensor network by allowing low-resolution streams from multiple nodes to be fused at a central processing node in order to produce an enhanced resolution speech signal. Simulations and experimental results with real microphone signals are presented.
