Directional and Steerable Antennas for Optimizing Networks
PIs: Douglas Sicker and Dirk Grunwald
As the demand for wireless networks grows, the research community continues to seekmethods for improving network performance. On method for improving network throughput involves using directional antennas to increase signal gain and/or decrease interference. Our work in this area focuses on real-world development and evaluation of directional and phased array antenna systems. To this end, we have built the first large-scale testbed of outdoor phased array antennas, suggested new models for directional antenna use in simulations based on measurements, and have proposed new protocols that optimize their behavior in both time and space.
