Demo: Enabling AGILE spectrum adaptation in commercial 802.11 WLAN deployments
(2014)
In this work, we present the AGILE Spectrum Adaptation system that is able to dynamically tune the channel central frequency and bandwidth of wireless links in an adaptive to the interference and trafic conditions way. The ...
An efficient probing mechanism for next generation mobile broadband systems
(2012)
Opportunistic scheduling exploits multiuser diversity for improving the performance of wireless systems. However, it requires instantaneous channel state information (CSI) to be available at the transmitter side. Since ...
Optimal jamming attack strategies and network defense policies in wireless sensor networks
(2010)
We consider a scenario where a sophisticated jammer jams an area in which a single-channel random-access-based wireless sensor network operates. The jammer controls the probability of jamming and the transmission range in ...
Online energy consumption monitoring of wireless testbed infrastructure through the NITOS EMF framework
(2013)
Development of energy-efficient protocols and algorithms requires in-depth understanding of the power consumption characteristics of real world devices. To this aim, energy efficiency analysis is performed by the research ...

Experimental evaluation and comparative study on energy efficiency of the evolving IEEE 802.11 standards
(2014)
Over the last decade, the IEEE 802.11 has emerged as the most popular protocol in the wireless domain. Since the release of the first standard version, several amendments have been introduced in an effort to improve its ...
Measurement aggregation and routing techniques for energy-efficient estimation in wireless sensor networks
(2010)
Wireless sensor networks are fundamentally different from other wireless networks due to energy constraints and spatial correlation among sensor measurements. Mechanisms that efficiently compress and transport sensor data ...
The Role of Aggregators in Smart Grid Demand Response Markets
(2013)
The design of efficient Demand Response (DR) mechanisms for the residential sector entails significant challenges, due to the large number of home users and the negligible impact of each of them on the market. In this ...
Medium access games: The impact of energy constraints
(2011)
We consider random medium access schemes for devices that support sleep modes, i.e. turning off electronic compartments for energy saving. Due to hardware limitations, sleep mode transitions cannot occur at the medium ...
Maximum-Throughput Access Control in Wireless LANs Through Max-Weight-Inspired Policies
(2010)
The design of efficient medium access control (MAC) protocols that are backward compatible to legacy IEEE 802.11-based protocols is a central issue in the literature. This paper draws inspiration from utility-driven ...
