Layered multicast rate control based on lagrangian relaxation and dynamic programming
(2004)
In this paper, we address the rate control problem for layered multicast traffic, with the objective of solving a generalized throughput/fairness objective. Our approach is based on a combination of lagrangian relaxation ...
On multicast beamforming and admission control for UMTS-LTE
(2008)
Transmit beamforming for physical layer multicasting is emerging as an appealing transmission modality for next-generation cellular wireless systems, notably UMTS-LTE. Optimal design of the transmit beamformer(s) from a ...
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 ...
Joint multiuser downlink beamforming and admission control: A semidefinite relaxation approach
(2007)
Multiuser downlink beamforming under quality of service (QoS) constraints has attracted considerable interest in recent years, because it is particularly appealing from a network operator's perspective (e.g., UMTS, 802.16e). ...
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 ...
Downlink multi-user transmission for higher user speeds in IEEE 802.16m
(2009)
A dynamic resource allocation algorithm with beam steering is evaluated for providing broadband wireless access to mobile users of the emerging IEEE 802.16m air interface standard. Thanks to our design, the coverage area ...
A new slicing scheme for efficient use of wireless testbeds
(2009)
The gradually growing need for testbed use so as networking algorithms to be validated in real environments, has given rise to optimal utilization of testbed resources. Despite the fact that, many laboratories around the ...
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 ...
Lightweight cross-layer control algorithms for fairness and energy efficiency in CDMA Ad-Hoc networks
(2006)
We consider a CDMA wireless ad - hoc network in high SINR regime. We introduce a suite of cross - layer algorithms for joint flow control, routing, scheduling and power control. algorithms guarantee forwarding of all ...
