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 ...
Design, architecture and implementation of a resource discovery, reservation and provisioning framework for testbeds
(2015)
Experimental platforms (testbeds) play a significant role in the evaluation of new and existing technologies. Their popularity has been raised lately as more and more researchers prefer experimentation over simulation as ...
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 ...
Adaptive radio resource management in a sectored cell for broadband wireless access systems
(2010)
In this work, we analyze the performance of a multi-user sectored MIMO/OFDMA system under the limited feedback constraint. Dynamic radio resource management methods are used to a reuse-one sectorized cell in order to reduce ...
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 ...
