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

Recent research results show that there are significant gains in throughput to be realized
with directional transmission and directional reception compared to using omnidirectional; …

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 …

Directional antenna has received intensive research interests in recent years due to its
potential to increase communication efficiency and resilience to interference and jamming …

We address deafness and directional hidden terminal problem that occur when MAC
protocols are designed for directional antenna based wireless multi-hop networks. Deafness …

Wireless communication is one of the fastest growing fields of communication industry.
Cellular phones have shown the drastic exponential growth from the last decade and this …

Directional antennas have been shown to have the potential to provide dramatic increases
in throughput and reduction in delay, while simultaneously requiring lower transmit power …

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 …

Motivated by recent interest in directional antennas for WSNs, we propose a Four-Beam
Patch Antenna (FBPA) designed to meet the size, cost and complexity constraints of sensor …

Switched beam antennas are an attractive extension to indoor wireless LANs due to their
increased signal gain in a chosen direction; the gain can be exploited for improving wireless …
