  • Abstract
    Sensor network-based voice communications research has been focused on realizing the voice call. In recent years, there are the needs to improve call quality in voice communication based on sensor network. Therefore in this paper, we propose the TDMA/TDD MAC which is based on IEEE 802.15.4 PHY in order to realize a clean voice calls which are based on sensor network. In addition, the results were verified by comparing MOS of the proposed system and the previous system.
