Protocols for beamforming antennas usually direct the beam toward the respective
communication partner. This requires significant coordination between nodes and results in …

This paper analyzes the effects of beamforming on the connectivity of wireless ad hoc
networks. We study different beamforming techniques using the uniform circular array as the …

We show that randomized beamforming is a simple yet efficient communication strategy in
wireless multihop networks if no neighbor location information is at hand. Already small …

We propose a dynamic blind beamforming scheme which allows to benefit from antenna
directivity in large mobile ad hoc networks while avoiding heavy feedback to track mobile …

Via collaborative beamforming, nodes in a wireless network are able to transmit a common
message over long distances in an energy efficient fashion. However, the process of making …

Future wireless networks will be characterized by heterogeneous network architectures, with
multihop communication as an important aspect. It is not clear yet how much multihop …

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 …

In this paper, we present an analytical model for evaluating the impact of shadowing and
beamforming on the connectivity of wireless ad hoc networks accommodating nodes …

Random beamforming, where each node selects a main beam direction without any
coordination with other nodes, has been proposed as a simple technique to improve …

Distributed beamforming in wireless ad hoc networks has the promise of greatly improving
network throughput. However, unlike traditional beamforming from a fixed array, the random …
