Abstract :
As increasing the need of multimedia such as voice data using wireless sensor network, the research about voice over sensor network (VoSN) has been conducted widely. In this paper, we design a full-duplex voice mixer for multi-user VoSN system as group communication and describe the issues about implementation such as hardware configuration, medium access control (MAC) protocol, and synchronization among multiple users. To measure the quality of designed system, we conduct an experiment using sine wave. As result of an experiment, we expect that a variety of applications can be developed using presented system.
