Abstract

For increasing demands on transceiving coverage, reliability and high resolution of sensing data in modern wireless sensor network applications, a novel digital transceiver scheme for wireless sensor node with integration of WiMAX PHY, QoS, and low-density parity check (LDPC) code had been proposed. It will be 67% energy saving to support high gain sensing amplifier thus to provide high resolution digitization of sensing data. With WiMAX based regulation, 30 mile transmission range and 74 Mbps data rate for long range and high data rate wireless sensor networks can be achieved.
