Abstract

This paper evaluates transmission performance and power-saving effect of the collaborative beamforming for wireless ubiquitous network systems. The evaluation of power-saving includes the power consumption for signal transmission to collaborative sensors in beamforming. The simulation result shows that the total power consumption of the beamforming with 3 collaborative sensors can be decreased to about 1/2 compared with that of a transmitting sensor without the beamforming in free-space propagation channels. In typical mobile propagation channels with shadowing, the total power consumption of the beamforming by using 3 collaborative sensors can be reduced to 1/7 of that without the beamforming. The above results confirm that the collaborative beamforming can be achieve lower power consumption, and greatly contributes to realize low-power transmission in wireless sensor network systems. copyright
