A design of data storage using voice over sensor network(VoSN) systems

Research line actively in the field of multi-media voice and recently emerged from the application of existing home network, remote control, and automatic sensor by using the feature low power consumption, low-speed data, low-cost of IEEE802.15.4. In this paper, we designed a TDMA / TDD MAC of IEEE802.15.4 PHY based for voice storage system using a sensor network of existing; we had developed a hardware Half-duplex system. Further, it was confirmed that in order to analyze the voice quality, it is possible to measure Mean Opinion Score (MOS), as compared to voice conventional systems, to extend the application solution in a production environment.
