This paper presents ARC (Adaptive Range Control), a communication range control
mechanism using directional antennas to be implemented across multiple layers. ARC uses …

Previous research in wireless ad hoc networks typically assumes the use of omnidirectional
antennas at all nodes. With omnidirectional antennas, while two nodes are communicating …

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

We investigate the possibility of using directional antennas for medium access control in
wireless ad hoc networks. Previous research in ad hoc networks typically assumes the use …

A medium access control (MAC) protocol (NULLHOC) for ad hoc networks of nodes with
antenna arrays is presented. The antenna array is used for transmit and receive …

Traditionally medium access control protocols for ad hoc networks have been designed for
nodes using omni directional antennas. Through the use of directional antennas, it is …

In recent years, the use of directional antennas in wireless networks has been widely
studied. Since the medium access control (MAC) protocol of the IEEE 802.11 standard was …

We propose a medium access control (MAC) protocol for an ad hoc network of mobile
wireless terminals that are equipped with multiple directional antennas. Use of directional …

This paper presents the first analytical model of wireless ad hoc networks that considers the
impact of realistic antenna-gain patterns on network performance. As such, our modeling …
