Auction-based scheduling of wireless testbed resources
(2014)Experimentation in testbeds is gaining increasing ground as a necessary validation step for every theoretical study in communication networks. However, the first-come-first-served policy employed today by most testbeds ... -
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 ... -
Demonstration of a video-aware multicast opportunistic routing protocol over 802.11 two-hop mesh networks
(2014)In this demo paper, we demonstrate and evaluate a novel Opportunistic Routing (OR) protocol for video multicast, namely Video-aware Multicast Opportunistic Routing (ViMOR), over 802.11 two-hop mesh networks. OR exploits ... -
A demonstration of multirate multicast over an 802.11 mesh network
(2014)This demo presents a novel multirate multicast scheme for video delivery to wireless users. We demonstrate an adaptive scheme that combines differential backlog scheduling and intelligent packet dropping, both based on ... -
A demonstration of video over a user centric prioritization scheme for wireless LANs
(2008)Due to the unreliable nature of the wireless medium, provisioning of the Quality of Service (QoS) in wireless LANs is by far more complicated than in wired networks. In this demo we show the efficiency of a new QoS support ... -
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 ... -
Exploiting OpenFlow resources towards a content-centric LAN
(2013)The efficient utilization of emerging new technologies for the sake of implementing attracting and novel network architectures is a major research challenge. As traditional addressing schemes seem to be rather inefficient ... -
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. ... -
Integrating FlowVisor access control in a publicly available OpenFlow testbed with slicing support
(2012)OpenFlow technology has recently attracted a lot of attention in the networking research community, as the ability to control the forwarding plane of a switch through software opens new exciting capabilities for protocol ... -
Multirate multicast: Optimal algorithms and implementation
(2014)Multirate multicast improves user quality but complicates network optimization. This paper introduces a novel control scheme to dynamically optimize multirate multicast. We present MMT, an adaptive policy which combines ... -
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 ... -
Optimization driven multi-hop network design and experimentation: The approach of the FP7 project OPNEX
(2012)The OPNEX project exemplifies system and optimization theory as the foundations for algorithms that provably maximize capacity of wireless networks. The algorithms termed in abstract network models have been converted to ... -
Video-aware multicast opportunistic routing over 802.11 two-hop mesh networks
(2014)In this paper, we propose and characterize the performance of a novel video-aware Opportunistic Routing (OR) algorithm for multicast, using a one-hop and two-hop forwarding scheme in 802.11 mesh networks. We believe that ... -
Wireless network virtualization: The CONTENT project approach
(2014)Undoubtedly, SDN has the potential to fundamentally change the way end-to-end networks are provisioned and designed. By introducing programmability into networking, the handling of network changes and network provisioning ...
