Design, architecture and implementation of a resource discovery, reservation and provisioning framework for testbeds
(2015)
Experimental platforms (testbeds) play a significant role in the evaluation of new and existing technologies. Their popularity has been raised lately as more and more researchers prefer experimentation over simulation as ...
Adaptive radio resource management in a sectored cell for broadband wireless access systems
(2010)
In this work, we analyze the performance of a multi-user sectored MIMO/OFDMA system under the limited feedback constraint. Dynamic radio resource management methods are used to a reuse-one sectorized cell in order to reduce ...
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 ...
Optimizing video quality in dense small-cell wireless networks with packet overhearing
(2014)
The heterogeneous wireless network (HetNet) paradigm is based on the deployment of low power small cell base stations (SCBS) close to the user in parallel with a macrocell BS (MBS) that provides umbrella coverage. However, ...
On the applicability of steerable beams in LTE-Advanced networks with high user mobility
(2012)
This article deals with the problem of applying scanning narrow beams to long-term evolution (LTE)-advanced networks that include in their coverage areas fast moving mobiles. The system scenario is assumed to include eNodeBs ...
Sustainability of service provisioning systems under attack
(2013)
We propose a resource allocation model that captures the interaction between legitimate users of a distributed service provisioning system with malicious intruders attempting to disrupt its operation. The system consists ...
Enhancing WPS security
(2012)
The main concern on the use of wireless technologies is security, due to the nature of the medium. User awareness in order to implement efficient security configurations is an important requirement raised by the technology, ...
Scheduling with pairwise XORing of packets under statistical overhearing information and feedback
(2012)
We study the problem of scheduling packets from several flows traversing a given node which can mix packets belonging to different flows. Practical wireless network coding solutions depend on knowledge of overhearing events ...
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 ...
Optimal cooperative content placement algorithms in hierarchical cache topologies
(2012)
The tremendous growth in the use of the World Wide Web and the expansion of Video On Demand and IPTV services increase the bandwidth demands, enforcing the creation of congestion in Internet's links and the experience of ...
