Handling asymmetry in gain in directional antenna equipped ad hoc networks
(2005)
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 increased number of collisions; this effect is primarily ...
Enabling sensing and mobility on wireless testbeds
(2012)
The inherent inability of simulation models to adequately express factors such as wireless signal propagation etc., can lead to incomplete evaluation of wireless protocols and applications. Thus, testing of proposed schemes ...
LAC: Load-aware channel selection in 802.11 WLANs
(2008)
Dense deployments of hybrid WLANs result in high levels of interference and low end-user throughput. Many frequency allocation mechanisms for WLANs have been proposed by a large body of previous studies. However, none of ...
Dynamic cross-layer association in 802.11-based mesh networks
(2007)
In IEEE 802.11-based wireless mesh networks a user is associated with an access point (AP) in order to communicate and be part of the overall network. The association mechanism specified by the IEEE 802.11 standard does ...
Cooperative handoff in wireless networks
(2008)
In 802.11-based wireless networks the stations (STAs) are associated with the available access points (APs) and communicate through them. In traditional handoff schemes the STAs get information about the active APs in their ...
A MAC protocol for full exploitation of directional antennas in ad-hoc wireless networks
(2003)
Directional antennas in ad hoc networks offer many benefits compared with classical omnidirectional antennas. The most important include significant increase of spatial reuse, coverage range and subsequently network capacity ...
