Directional antennas in ad hoc networks offer many benefits compared with classical
omnidirectional antennas. The most important include significant increase of spatial reuse …

Traditional MAC protocols used in ad hoc networks employ omnidirectional antennas.
Directional antennas have emerged as an alternative due to their capability of spatial reuse …

This paper addresses the issue of deafness in directional antennas for wireless ad hoc
networks. Deafness is caused when a node X repeatedly attempts to communicate with …

Many MAC sub-layer protocols for supporting the usage of directional antennas in ad hoc
networks have been proposed in literature. However, there remain two open issues that are …

Recently, MAC protocols using directional antennas for wireless ad hoc networks that are
based on and similar to IEEE 802.11 type WLAN have been proposed. These protocols …

Using directional antennas can be beneficial for wireless ad hoc networks consisting of a
collection of wireless hosts. To best utilize directional antennas, a suitable medium access …

The deployment of traditional higher layer protocols (especially the IEEE 802.11 MAC
protocol at the MAC layer) with directional antennae could lead to problems from an …

We propose a novel medium access control (MAC) algorithm using pure directional
transmission and reception for mobile wireless ad hoc networks with directional antennas …

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 …

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 …
