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 ...
A demonstration of video over an IEEE 802.11 compliant version of the enhanced-backpressure algorithm
(2012)
This demo presents a novel routing and scheduling scheme, named Enhanced-Backpressure over WiFi (EBoW), that obviously outperforms the dominant approach of a shortest-path routing (SRCR) combined with the classic CSMA/CA ...
Client and server games in peer-to-peer networks
(2009)
We consider a content sharing network of noncooperative peers. The strategy set of each peer comprises, (i) client strategies, namely feasible request load splits to servers, and (ii) server strategies, namely scheduling ...
Cross-testbed experimentation using the Planetlab-NITOS federation
(2012)
Federation of network testbeds has been identified as a key goal in the experimental testbeds community, leading to a recent activity burst in this research field. In this demo, we describe a federated experiment between ...
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 ...
Implementation and end-to-end throughput evaluation of an IEEE 802.11 compliant version of the enhanced-backpressure algorithm
(2012)
Extensive work has been done in wireless multihop routing with several ideas based on shortest path or load balancing routing algorithms, that aim at minimizing end-to-end delay or maximizing throughput respectively. ...
Online assessment of sensing performance in experimental spectrum sensing platforms
(2014)
Dynamic Spectrum Access aims at exploiting underutilized frequency bands towards improving wireless network performance. In this context, spectrum sensing is employed, in order to monitor spectrum occupancy and drive ...
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 ...
The mutual benefits of primary-secondary user cooperation in wireless cognitive networks
(2014)
In cognitive radio networks, secondary users (SUs) may cooperate with the primary user (PU) in order to obtain more transmission opportunities and thus maximize their throughput. The synergy consists in the following: the ...
Control and optimization meet the smart power grid: Scheduling of power demands for optimal energy management
(2012)
The smart power grid harnesses information and communication technologies to enhance reliability and enforce sensible use of energy through effective management of demand load. We envision a scenario with real-time ...
