Wireless ad hoc networks are typically assumed to be equipped with omnidirectional
antennas. With advances in signal processing and antenna technology, it may now be …

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 …

Wireless multihop networks are gaining popularity in applications such as mesh networks,
wireless backbones, and sensor networks. Typically, communication protocols designed for …

We examine in this paper the benefits of beamforming techniques in ad hoc networks. We
first devise a novel MAC paradigm for ad hoc networks when using these techniques in …

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 …

Beamforming antennas have been shown to improve spatial reuse in wireless networks.
Protocols that aim to exploit beamforming antennas have leveraged benefits from directional …

Directional antennas have shown to be advantageous in an ad hoc wireless network over
traditional omnidirectional antennas to provide higher network throughput because they can …

In this paper, we evaluate through analytical modeling, the performance of ad hoc networks
when the nodes are endowed with M-element antenna array. We first derive the loss …

Publisher Summary Communication is maintained by the transmission of data packets over
a common wireless channel. The absence of any fixed infrastructure such as an array of …

Directional antennas offer tremendous potential for improving the performance of ad hoc
networks. Harnessing this potential, however, requires new mechanisms at the medium …
