VIPSec defined
(2008)
Secure end-to-end information exchange is a constant challenge in electronic communications. Novel security architectures and approaches are proposed constantly, to be followed by announcements of sophisticated attack ...
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 ...
Joint QoS multicast power / admission control and base station assignment: A geometric programming approach
(2008)
The joint power control and base station (BS) assignment problem is considered under Quality-of-Service (QoS) constraints. If a feasible solution exists, the problem can be efficiently solved using existing distributed ...
Cooperation and directionality: A co-opdirectional MAC for wireless ad hoc networks
(2007)
Advances in cooperative communications and directional antenna design so far have taken place in parallel, if not in isolation from each other. To explore the role they may play in the next generation of wireless networks, ...
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 ...
Distributed dynamic scheduling for end-to-end rate guarantees in wireless ad hoc networks
(2005)
We present a framework for the provision of deterministic end-to-end bandwidth guarantees in wireless ad hoc networks. Guided by a set of local feasibility conditions, multi-hop sessions are dynamically offered allocations, ...
Maxmin fair scheduling in wireless ad hoc networks
(2005)
We investigate from an algorithmic perspective the maxmin fair allocation of bandwidth in wireless ad hoc networks. We formalize the maxmin fair objective under wireless scheduling constraints, and present a necessary and ...
Providing quality of service guarantees in wireless LANs compliant with 802.11e
(2005)
Quality of Service (QoS) support is a key attribute of a broadband communication system and is missing in 802.11-based wireless LANs. Recognizing the need, Task Group e (TGe) is work-ins! towards 802.11e, an evolution of ...
Joint optimal access point selection and channel assignment in wireless networks
(2007)
In wireless cellular networks or in other networks with single-hop communication, the fundamental access control problem pertains to access point (AP) selection and channel allocation for each user. For users in the coverage ...
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 ...
