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 ...
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 ...
Convex Approximation Algorithms for Back-Pressure Power Control
(2012)
Throughput-optimal multihop wireless network operation entails a key physical-layer optimization problem: maximizing a weighted sum of link rates, with weights given by the differential queue backlogs. This emerges in joint ...
Convex approximation techniques for joint multiuser downlink beamforming and admission control
(2008)
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., UNITS, 802.16e). ...
