An 802.11k Compliant Framework for Cooperative Handoff in Wireless Networks
(2009)
In IEEE 802.11-based wireless networks, the stations (STAs) are associated with the available access points (APs) and communicate through them. In traditional hando. schemes, the STAs get information about the active APs ...
Cross-layer design for power efficiency and QoS provisioning in multi-hop wireless networks
(2006)
In recent years, it has become common consensus that independent consideration of communication layers often turns out to be inadequate in terms of providing the desired quality of service (QoS) and power efficiency in ...
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 ...
Distributed topology construction of Bluetooth wireless personal area networks
(2005)
Bluetooth, a wireless technology based on a frequency-hopping physical layer, enables portable devices to form short-range wireless ad hoc networks. Bluetooth hosts are not able to communicate unless they have previously ...
Layered multicast rate control based on Lagrangian relaxation and dynamic programming
(2006)
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 ...
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). ...
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). ...
