AIDA: Distributed Beamforming in Sensor Networks


This project aims to create a new sensor network architecture, AIDA, that uses antenna arrays of the distributed sensor nodes to create directional radio waves that can reach order-of-magnitude farther than individual antennas of the sensor nodes. Such a distributed antenna array is created by aligning antennas of multiple sensor nodes and transmitting the same information simultaneously at different phases. Because of wave reinforcement and cancellation, the signals can be highly directional and reach much longer distances than that by each individual antenna. While the concept of distributed antenna arrays has been studied theoretically recently, applying such antenna arrays to wireless sensor networks has not been fully explored.


This project is sponsored by the National Science Foundation under Grant CNS-0721873.
