Nodes, using CSMA/CA type medium access control (MAC) protocols (eg IEEE 802.11 e)
and omnidirectional antennas, in an ad-hoc network may not be able to transmit packets to …

The most widely used standard for wireless networks is the IEEE 802.11. In 802.11, dense
deployment of Access Points (APs) is needed to meet customers' demands. The installation …

We present an outdoors 802.11 a testbed based on off-the-shelf components that we used
for multi-radio node experimentation. This is the first such testbed, to our knowledge …

This paper studies the measured behavior of point-to-point 802.11 a links at low and high
antenna elevations. The purpose of the project is to investigate the possibility of using …

Directional antennas have been introduced to improve the performance of 802.11 based
wireless networks. Station equipped with directional antennas can beamform data in a …

Multi-channel wireless networks are being studied as a means to increase wireless network
capacity. The implicit assumption is that network throughput increases in direct proportion …

This paper tackle the problem of coverage in IEEE 802.11 in mesh mode. Instead of
omnidirectional coverage, we propose to use directional coverage that can increase the …

When directional antennas are used in 802.11 based wireless LANs, higher network
capacity is often accompanied with more collisions. This is due to the enhanced hidden …
