CDR-MAC: A protocol for full exploitation of directional antennas in ad hoc wireless networks
(2008)In this paper, we propose a new Medium Access Control (MAC) protocol for full exploitation of directional antennas in wireless networks. The protocol introduces a circular directional transmission of the Request To Send ... -
Contention and traffic load-aware association in IEEE 802.11 WLANs: Algorithms and implementation
(2011)Efficient association of a station with the appropriate access point has always been a challenging problem. The standard approach of considering only the Received Signal Strength, has recently been substituted by more ... -
Detecting IEEE 802.11 MAC layer misbehavior in ad hoc networks: Robust strategies against individual and colluding attackers
(2007)Selfish behavior at the Medium Access (MAC) Layer can have devastating side effects on the performance of wireless networks, with effects similar to those of Denial of Service (DoS) attacks. In this paper we consider the ... -
Joint beamforming and channel selection for multicast IEEE 802.11n WLANs
(2008)Multicast transmission over WLANs is becoming a popular application. IEEE 802.11n technology is developed due to the ever increasing demand for higher data rate and Quality of Service (QoS). However, there is an unmanaged ... -
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 ... -
New prioritization schemes for QoS provisioning in 802.11 wireless networks
(2008)Due to the unreliable nature of the wireless medium, provisioning of Quality of Service (QoS) in wireless LANs is far more complicated than in wired networks. In order to address this challenge, IEEE 802.11e defines a ... -
Novel metrics and experimentation insights for dynamic frequency selection in wireless LANs
(2011)The rapidly increasing popularity of IEEE 802.11 WLANs has created unprecedented levels of congestion in the unlicensed frequency bands, especially in densely populated urban areas. Performance experienced by end-users in ...
