C2M: Mobile data offloading to mesh networks
(2014)As the unprecedented growth of mobile data traffic places significant strain on cellular networks, alternative plans for exploiting already existing and under-utilized wireless infrastructure, become quite attractive. In ... -
Cross-Layer Antenna Beamforming and Power Control in Wireless Uplinks
(2009)We consider backlog-driven power control and antenna beamforming as a means to maximize network throughput in a wireless uplink, where a base station receives with an antenna array from single-antenna wireless users. ... -
A demonstration of a management tool for assessing channel quality information in wireless testbeds
(2011)The gradually growing need for testbed use so as networking algorithms to be validated in real environment, has given rise to optimal utilization of testbed resources. Towards this direction, we present a new management ... -
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 ... -
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 ... -
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 ... -
Interconnection of geographically distributed wireless mesh testbeds: Resource sharing on a large scale
(2011)Creating large scale testbeds for evaluating wireless mesh technologies and protocols, and for testing their ability to support real world applications in realistic environments, is a crucial step towards the ultimate ... -
Methodology and tools for measurements on wireless testbeds: The NITOS approach
(2013)Since its establishment in 2009, the Network Implementation Testbed using Open Source drivers (NITOS) wireless testbed has been extensively used in several research projects for the experimental evaluation of protocols and ... -
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 ... -
A new slicing scheme for efficient use of wireless testbeds
(2009)The gradually growing need for testbed use so as networking algorithms to be validated in real environments, has given rise to optimal utilization of testbed resources. Despite the fact that, many laboratories around the ... -
On the implementation of relay selection strategies for a cooperative diamond network
(2013)In this paper, we present an implementation design of a TDMA protocol for the canonical diamond-topology network containing a source, two relays and a destination (single unicast session). Getting inspired by the established ... -
TLQAP: A topology and link quality assessment protocol for efficient node allocation on wireless testbeds
(2009)In this paper we present Topology and Link Quality Assessment Protocol (TLQAP), which we have implemented as a wireless testbed management framework component, that is used to inspect link quality between wireless testbed ... -
Towards maximizing wireless testbed utilization using spectrum slicing
(2011)As experimentation becomes one of the de-facto approaches for benchmarking, researchers are turning to testbeds to test, review and verify their work. As a result, several research laboratories build wireless testbeds, in ...
