Abstract
A Time Division Duplex (TDD) approach is demonstrated for voice communication in the environment of wireless sensor networks. The architecture of the Voice Wireless Sensor Networks (VoWSN) is presented and the hardware designing of Voice Node and Gateway Node are described in detail. Voice quality of different scenarios such as indoor, corridor, corner and outdoor are tested. It is resulted that good voice quality can be obtained in short distance or line of sight with no obstacle. The Routing Node and Gateway Node is introduced to relay in the case of long distance or with obstacles in the channel path.
