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 ...
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 ...
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 ...
Cross-layer adaptive techniques for throughput enhancement in wireless OFDM-based networks
(2006)
Although independent consideration of layers simplifies wireless system design, it is inadequate since: 1) it does not consider the effect of co-channel user interference on higher layers; 2) it does not address the impact ...
Approximation Algorithms for Mobile Data Caching in Small Cell Networks
(2014)
Small cells constitute a promising solution for managing the mobile data growth that has overwhelmed network operators. Local caching of popular content items at the small cell base stations (SBSs) has been proposed to ...
Adaptive channel assignment in SDMA-based wireless LANs with transceiver resource limitations
(2006)
Beamforming with adaptive antenna arrays is the most promising means for increasing data rates of wireless systems, since it enables channel reuse by several users in a cell through space division multiple access (SDMA). ...
