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. ...
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, ...
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 ...
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 ...
A delay based optimization scheme for peak load reduction in the smart grid
(2012)
A measurement campaign based on commodity wireless sensors shows that the majority of thermostatic loads in a user premise are described by periodic pulse waves. The superposition of these loads results to high peak power ...
Experimenting with P2P traffic optimization for wireless mesh networks in a federated OMF-PlanetLab environment
(2011)
The ultimate success of the Wireless Mesh Network paradigm (WMN) in large scale deployments depends on the ability to test it in real world scenarios. A typical application scenario which is worth to be investigated in ...
Energy aware buffer aided cooperative relay selection
(2014)
In this paper we evaluate an energy-aware relay selection mechanism which exploits channel state information and the availability of buffers at relays to perform flexible relaying based on a backpressure-driven optimization ...
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 ...
A demonstration of a relaying selection scheme for maximizing a diamond network's throughput
(2012)
We demonstrate a queue-aware algorithm studied in a diamond network topology. This algorithm's decisions are obtained from an analytical optimization framework relying on our technical work [4] and we devise an implementation ...
