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 ...
Low-complexity beamforming techniques for IEEE 802.11n WLANs
(2009)
The impetus of the present study is to describe a downlink beamforming method that increase spectrum efficiency and significantly reduces implementation complexity and power consumption compare to beamforming technique at ...
End-to-end bandwidth guarantees through fair local spectrum share in wireless ad-hoc networks
(2003)
Sharing the locally common spectrum among the links of the same vicinity is a fundamental problem in wire-less ad-hoc networks. Lately some scheduling approaches have been proposed that guarantee fair share of the bandwidth ...
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 ...
On the structure and evolution of vehicular networks
(2009)
Vehicular ad hoc networks have emerged recently as a platform to support intelligent inter-vehicle communication and improve traffic safety and performance. The road-constrained and high mobility of the vehicles, their ...
Maximum lifetime routing in wireless sensor networks
(2004)
A routing problem in static wireless ad hoc networks is considered as it arises in a rapidly deployed, sensor based, monitoring system known as the wireless sensor network. Information obtained by the monitoring nodes needs ...
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 ...
