Cooperation and information replication in wireless networks
(2016)A significant portion of today's network traffic is due to recurring downloads of a few popular contents. It has been observed that replicating the latter in caches installed at network edges-close to users- can drastically ... -
Cooperative live video multicast for small cell base stations with overlapping coverage
(2016)In this paper, we present a cooperative video multicast protocol for densely deployed small cells. We assume that the small cell Base Stations (BS) have overlapping coverages and they are allowed to have interfering ... -
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 ... -
Exploiting Caching and Multicast for 5G Wireless Networks
(2016)The landscape toward 5G wireless communication is currently unclear, and, despite the efforts of academia and industry in evolving traditional cellular networks, the enabling technology for 5G is still obscure. This paper ... -
In-Network Congestion Control for Multirate Multicast
(2016)We present a novel control scheme that dynamically optimizes multirate multicast. By computing the differential backlog at every node, our scheme adaptively allocates transmission rates per session/user pair in order to ... -
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 ... -
Joint multicast beamforming and admission control
(2007)Wireless multicasting is quickly emerging as an important enabling technology for mass content distribution to mobile hand-held devices. With channel state information at the transmitter, it is possible to tailor transmissions ... -
Joint QoS multicast power / admission control and base station assignment: A geometric programming approach
(2008)The joint power control and base station (BS) assignment problem is considered under Quality-of-Service (QoS) constraints. If a feasible solution exists, the problem can be efficiently solved using existing distributed ... -
Layered multicast rate control based on lagrangian relaxation and dynamic programming
(2004)In this paper, we address the rate control problem for layered multicast traffic, with the objective of solving a generalized throughput/fairness objective. Our approach is based on a combination of lagrangian relaxation ... -
Link scheduling for multiple multicast sessions in distributed wireless networks
(2013)In this letter we investigate link scheduling algorithms for throughput maximization in multicast wireless networks. According to our system model, each source node transmits to a multicast group that resides one hop away. ... -
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 ... -
Multicast-aware caching for small cell networks
(2014)The deployment of small cells is expected to gain huge momentum in the near future, as a solution for managing the skyrocketing mobile data demand growth. Local caching of popular files at the small cell base stations has ... -

National survey of morbidity and risk factors (EMENO): Protocol for a health examination survey representative of the adult Greek population
(2019)Background: Main causes of death in Greece are cardiovascular diseases (CVDs), malignant neoplasms, respiratory diseases, and road traffic crashes. To assess the population health status, monitor health systems, and adjust ... -
On multicast beamforming and admission control for UMTS-LTE
(2008)Transmit beamforming for physical layer multicasting is emerging as an appealing transmission modality for next-generation cellular wireless systems, notably UMTS-LTE. Optimal design of the transmit beamformer(s) from a ... -
Using multicast transfers in the replica migration problem: Formulation and scheduling heuristics
(2009)Performing replica migrations in the minimum possible time, also called the Replica Migration Problem (RMP), is crucial in distributed systems using replication. In this paper we tackle RMP when multicast transfers are ... -
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 ... -
Video-Aware Multicast Opportunistic Routing over 802.11 Two-Hop Mesh Networks
(2017)Opportunistic routing benefits from the broadcast nature of wireless communication and outperforms the packet losses occurring in a wireless environment, especially in the case of multicast. In this work, we present and ...
