Applying pressure management to reduce water losses in two greek cities' WDSs: Expectations, problems, results and revisions
(2014)An overall pressure management project applied in two (Kos and Kozani) different water distribution systems in Greece is presented. The two Water Utilities developed a pressure management strategy. In both cases, Watergems ... -
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 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 ... -
Interference mitigation in co-working IEEE 802.11n WLANs
(2009)In a densely deployed Wireless Local Area Network (WLAN) environment, Access Points (APs) could be so close to cause significant channel interference. In the next generation IEEE 802.11n WLANs, inter-cell interference ... -
Joint beamforming and channel selection for multicast IEEE 802.11n WLANs
(2008)Multicast transmission over WLANs is becoming a popular application. IEEE 802.11n technology is developed due to the ever increasing demand for higher data rate and Quality of Service (QoS). However, there is an unmanaged ... -
LAC: Load-aware channel selection in 802.11 WLANs
(2008)Dense deployments of hybrid WLANs result in high levels of interference and low end-user throughput. Many frequency allocation mechanisms for WLANs have been proposed by a large body of previous studies. However, none of ... -
A MAC protocol for full exploitation of directional antennas in ad-hoc wireless networks
(2003)Directional antennas in ad hoc networks offer many benefits compared with classical omnidirectional antennas. The most important include significant increase of spatial reuse, coverage range and subsequently network capacity ... -
Multicast transmission over IEEE 802.11n WLAN
(2008)With the advent of low-cost WLAN devices, the delivery of multimedia content is highly desirable. Such applications require high throughput and near-real time for quality viewing. The use of next-generation WLAN 802.11n ... -
New prioritization schemes for QoS provisioning in 802.11 wireless networks
(2008)Due to the unreliable nature of the wireless medium, provisioning of Quality of Service (QoS) in wireless LANs is far more complicated than in wired networks. In order to address this challenge, IEEE 802.11e defines a ... -
OmniStore: A system for ubiquitous personal storage management
(2006)As personal area networking becomes a reality, the collective management of storage in portable devices such as mobile phones, cameras and music players will grow in importance. The increasing wireless communication ... -
On the use of distributed directive antenna arrays in mobile OFDMA networks
(2011)Distributed Omni Antenna Systems (OASs) have been proposed to increase the capacity of Broadband Wireless Access (BWA) systems. We investigate the extension of such systems by employing distributed Directive Antenna Arrays ... -
Query sensitive storage for wireless sensor networks
(2009)Storage management in wireless sensor networks is an area that has started to attract significant attention, and several methods have been proposed, such as Local Storage (LS), Data-Centric Storage (DCS) and more recently ... -
Real-life paradigms of wireless network security attacks
(2011)Wirelesses Local Area Networks (WLANs) have become more prevalent and are widely deployed in many popular places like university campuses, cafés, airports, residences, etc. However, WLAN security is a very important but ... -
Software-Defined Optical Local Area Network Architecture And Priority Traffic Performance Analysis
(2022)A software-defined (SD) solution for optical LANs is presented in our study. The SD approach implements the control plane for the LAN servers orchestration in order for the data plane to adopt a slotted efficient MAC ... -
Wavelet-based compression with ROI coding support for mobile access to DICOM images over heterogeneous radio networks
(2009)Most of the commercial medical image viewers do not provide scalability in image compression and/or region of interest (ROI) encoding/decoding. Furthermore, these viewers do not take into consideration the special requirements ...
