Abstract
Beamforming antennas have the potential to provide a fundamental breakthrough in ad hoc network capacity. We present a broad-based examination of this potential, focusing on exploiting the longer ranges as well as the reduced interference that beamforming antennas can provide. We consider a number of enhancements to a conventional ad hoc network system, and evaluate the impact of each enhancement using simulation. Such enhancements include \aggressive" and \conservative " channel access models for beamforming antennas, link power control, and directional neighbor discovery. Our simulations are based on detailed modeling of steered as well as switched beams using antenna patterns of varying gains, and a realistic radio and propagation model. For the scenarios studied, our results show that beamforming can yield a 28% to 118% (depending upon the density) improvement in throughput, and up to a factor-of-28 reduction in delay. Our study also tells us which mechanisms are likely to be more eective and under what conditions, which in turn identi es areas where future research is needed.
