Wireless sensor networks typically require low cost devices and low power operations. Hence, such networks usually employ radios with only simple modulation techniques such as ASK, OOK and FSK. We propose a new energy efficient communication scheme for wireless sensor networks that is based on the ternary number system encoding of data. An efficient algorithm for conversion from binary to ternary...
Transmit beamforming is an energy-efficient wireless communication technique that allows a transmitter with two or more antennas to focus its bandpass signal in an intended direction. The idea of transmit beamforming has been extended to networks of single-antenna cooperative transmitters that pool their antenna resources and behave as a ldquodistributed beamformer.rdquo Unlike conventional transmit...
