Design of Mobile, Wireless (Ad Hoc) Networks Using Smart Antennas

"In the future, smart antennas will become commonplace in military communications due to strong performance advantages on the one hand, and the cost leverage provided by advances in digital signal processing and Moore's Law on the other hand. We propose todesign, simulate, and analyze distributed algorithms for efficient management of transmission resources in multihop mobile wireless networks with smart antennas. Building on our prior work on multibeam transmission and reception through sub-bandbeamforming, blind techniques for neighbor discovery that have a low probability of detection, and directional TDMA-based medium access control, we will demonstrate the potentially large performance improvements to be achieved in networks equipped withsmart antennas and algorithms that select, schedule, and reserve transmission resources so as to achieve the desired network characteristics as well as the requested quality of service for individual applications. We anticipate that our work willdemonstrate that networking with multiple-beam smart antennas has major benefits relative to networking with single-beam antennas, in both efficiency and ability of the network to provide the quality of service desired by mission-critical point-to-pointand multicast applications. We expect our technology to be a strong enabler of spectral reuse in both the defense and commercial sectors. The strong data-rate, LPD/AJ, and service provision benefits of harn
