Cooperation and directionality: A co-opdirectional MAC for wireless ad hoc networks
(2007)
Advances in cooperative communications and directional antenna design so far have taken place in parallel, if not in isolation from each other. To explore the role they may play in the next generation of wireless networks, ...
Joint beamforming and channel selection for multicast IEEE 802.11n WLANs
(2008)
Multicast transmission over WLANs is becoming a popular application. IEEE 802.11n technology is developed due to the ever increasing demand for higher data rate and Quality of Service (QoS). However, there is an unmanaged ...
An iterative double auction for mobile data offloading
(2013)
Mobile data offloading through complementary network technologies such as WiFi and femtocell can significantly alleviate network congestion and enhance users' QoS. In this paper we consider a market where mobile network ...
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 ...
The effect of caching in sustainability of large wireless networks
(2012)
We study the scalability of multihop wireless communications, a major concern in networking, for the case that users access content cached across the nodes. In contrast to the standard paradigm of randomly selected ...
Contention and traffic load-aware association in IEEE 802.11 WLANs: Algorithms and implementation
(2011)
Efficient association of a station with the appropriate access point has always been a challenging problem. The standard approach of considering only the Received Signal Strength, has recently been substituted by more ...
Optimization driven multi-hop network design and experimentation: The approach of the FP7 project OPNEX
(2012)
The OPNEX project exemplifies system and optimization theory as the foundations for algorithms that provably maximize capacity of wireless networks. The algorithms termed in abstract network models have been converted to ...
Distributed back-pressure power control for wireless multi-hop networks
(2012)
A key problem in wireless networking is how to choose a link activation schedule and associated powers in concert with routing decisions to optimize throughput. Back-pressure control policies are optimal in this context, ...
Carrier assignment algorithms for OFDM-based multi-carrier wireless networks with channel adaptation
(2008)
We study carrier assignment in a single-cell multiuser OFDM multi-carrier system so as to satisfy user rate requirements with minimal resources. Different users experience different quality in different carriers due to ...
Wireless networks capacity characterization and how to approach it
(2007)
Wireless systems possess attributes fairly different than those that formed the design guidelines of the Internet. Hence, novel approaches are needed for architecting networks that seamlessly integrate wired and wireless ...
