This paper addresses the issue of deafness and hidden terminal problem in a mobile ad hoc
networks (MANETs) using directional antennas. To minimize these effects, we propose a …

The move toward worldwide wireless communications continues at a remarkable pace, and
the antenna element of the technology is crucial to its success. With contributions from more …

Directional antennas provide angle-of-arrival information, which can be used for localization
and routing algorithms in wireless sensor networks. We briefly describe three classical …

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

Directional antennas are expected to provide significant improvements over omni-directional
antennas in wireless ad hoc networks. Directional MAC protocols, however, introduce new …

The use of directional antennas in ad hoc networks has received growing attention because
of its high spatial reuse and high antenna gains. The medium access control (MAC) protocol …

The use of smart antennas to increase mobile communications channels has re-ignited
research and development in the field. Practicing engineers are eager to discover more …

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 …

The capacity of wireless ad hoc networks is affected by two key factors: the interference
among concurrent transmissions and the number of simultaneous transmissions on a single …
