Abstract

The wireless sensor network (WSN) technology has been one of the most active research topics in the last several years. Besides sensing the environmental or physical data, there has been a growing need on supporting voice communication, particularly under emergency conditions, in WSNs. In this paper, we will conduct the implementation of voice codec on embedded system using multi-hopping ZigBee communication. The implementation issues, in terms of codec and transmission rate-dependence consideration, as well as the voice quality with multi-hopping are analyzed and evaluated for the designed test-bed.
