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 ...
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 ...
MNCM: A Critical Node Matching Approach to Scheduling for Input Buffered Switches With No Speedup
(2009)
In this paper, we use fluid model techniques to establish new results for the throughput of input-buffered switches. Dai and Prabhakar have shown that any maximal size matching algorithm with speedup of 2 achieves 100% ...
Fair distributed congestion control in multirate multicast networks
(2005)
We study fairness of resource allocation in multirate, multicast networks. In multirate networks, different receivers of the same multicast session can receive service at different rates. We develop a mathematical framework ...
On Multicast Beamforming for Minimum Outage
(2009)
The multicast beamforming problem is considered from the viewpoint of minimizing outage probability subject to a transmit power constraint. The main difference with the point-to-point transmit beamforming problem is that ...
Asynchronous TDMA ad hoc networks: scheduling and performance
(2004)
A common assumption of time division multiple access (TDMA)-based wireless ad hoc networks is the existence of network-wide slot synchronization. Such a mechanism is difficult to support in practice. In asynchronous TDMA ...
A Cross-Layer Framework for Association Control in Wireless Mesh Networks
(2009)
The user association mechanism specified by the IEEE 802.11 standard does not consider the channel conditions and the AP load in the association process. Employing the mechanism in its plain form in wireless mesh networks, ...
The impact of space division multiplexing on resource allocation: A unified treatment of TDMA,OFDMA and CDMA
(2008)
Space division multiple access (SDMA) with an antenna array at the transmitter is a promising means for increasing system capacity and supporting rate-demanding services. However, the presence of an antenna array at the ...
