    Abstract

    Audio data processing and transmission in Wireless Sensor Networks (WSNs) require systems which satisfy the equilibrium between heavy data traffic and limited resources. In the lossy nature of the network, transmission techniques matter to sustain a certain content validity to be preserved. Besides, data handling is a worth-stressing issue to sustain a decreased computation and traffic overhead. An admissible quality of the voice signals being gathered at the sink node is to be directly maintained with network transmission assessments. To this respect, basic characteristics of a voice signal must be compromised with network properties. In this study, we investigate the quality of voice signals sent through the homogeneously constructed multi-hop network in which recorded signal segments in the source node are touched with the counterparts expected to be collected in each hop with a transmission rating factor. The basic characteristics of the voice samples used in the testbed are essayed with different in-network qualifications that can directly affect the quality; so that a reasonable trade-off between voice quality and sensor network capabilities is tried to be proposed.
