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 ...
Efficient Batch and Adaptive Approximation Algorithms for Joint Multicast Beamforming and Admission Control
(2009)
Wireless multicasting is becoming increasingly important for efficient distribution of streaming media and location-aware services to mobile and hand-held devices, network management, and software updates over cellular ...
Achieving proportional fairness using local information in Aloha networks
(2004)
We address the problem of attaining proportionally fair rates using Aloha protocols at the medium access layer. We consider a wireless network where all nodes need not be in transmission ranges of each other. We show how ...
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 ...
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 ...
