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, ...
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 ...
Bargaining-based mobile data offloading
(2014)
The unprecedented growth of mobile data traffic challenges the performance and economic viability of today's cellular networks and calls for novel network architectures and communication solutions. Data offloading through ...
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 ...
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 ...
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 ...
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. ...
Hybrid data pricing for network-assisted user-provided connectivity
(2014)
User-provided connectivity (UPC) is a promising paradigm to achieve a low-cost ubiquitous connectivity. In this paper, we study a network-assisted UPC service model, where a mobile virtual network operator (MVNO) enables ...
Enabling mobile sensing through a DTN framework
(2013)
Participatory Sensing is the concept of distributed data collection by self-selected participants. By exploiting latest technology's smart devices, a large number of valuable information can be collected through embedded ...
New channel allocation techniques for power efficient WiFi networks
(2010)
Energy efficiency becomes evergreen than ever before. Over the last few years a significant research in wireless communications, aiming to enhance communications efficiency subject to constraint of power consumption, has ...
