Basic properties of wireless ad-hoc networks, such as connectivity, have traditionally been
analyzed and evaluated under the assumption that all nodes have homogeneous …

Directional antennas have the potential to provide a fundamental breakthrough in ad hoc
network capacity. Omni-directional nature of transmission restricts the network capacity …

In this paper, we present the design and evaluation of two techniques for routing
improvement using directional antennas in mobile ad-hoc networks. First, we use directional …

Directional antennas have the potential to provide a fundamental breakthrough in ad hoc
network capacity. Omni-directional nature of transmission restricts the network capacity …

We present a new distributed routing protocol for direct-sequence spread-spectrum, mobile
ad hoc packet radio networks that contain a mix of nodes with directional antennas and …

Previous research on directional antennas has been confined mostly to medium access
control. However, it is necessary to evaluate the impact of directional antennas on the …

This paper analyzes the impact of directional antennas in improving the transmission
capacity, defined as the maximum allowable spatial node density of successful …

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 …

Directional antennas can be useful in significantly increasing the capacity of wireless ad hoc
networks. With directional antennas, independent communications between nodes can …

We show that there is a trade-off among mobility, capacity, and delay in ad hoc networks.
More specifically, we consider two schemes for node mobility in ad hoc networks. We divide …
