Adaptive radio resource management in a sectored cell for broadband wireless access systems
(2010)In this work, we analyze the performance of a multi-user sectored MIMO/OFDMA system under the limited feedback constraint. Dynamic radio resource management methods are used to a reuse-one sectorized cell in order to reduce ... -
Adaptive Tile Parallelization for Fast Video Encoding in HEVC
(2017)As large multimedia providers rely more and more on Cloud resources to perform video coding and transcoding, designing fast and efficient coders that take advantage of parallelization, particularly for the new video standard ... -
Antiflooding prevention, protection, strategic environmental planning of aquatic resources and water purification: The case of Thessalian basin, in Greece
(2010)In the E.U. following the old 5th Environmental Action Program (EAP) of 1994 and the new 6th EAP for the sustainable development in 2001, we confront the strategic management problem of aquatic resources at the regional ... -
Asymptotically optimal policies for wireless networks with rechargeable batteries
(2008)We consider the problem of cross-layer resource allocation for single-hop, time-varying, wireless networks operating with rechargeable batteries under general arrival, channel and recharge processes. The objective is to ... -
Auction mechanisms for network resource allocation
(2010)In the autonomic Internet of the future, auction mechanisms arise as key methods for realizing efficient resource allocation. The major asset of auctions is their obliviousness to node utilities, which renders them capable ... -
Continuous replica placement schemes in distributed systems
(2005)The Replica Placement Problem (RPP) aims at creating a set of duplicated data objects across the nodes of a distributed system in order to optimize certain criteria. Typically, RPP formulations fall into two categories: ... -
Downlink mobile OFDMA resource allocation with minimum user rate requests
(2009)The problem of resource allocation (RA) in a downlink OFDMA system with minimum user rate requests is examined under the realistic scenario of partial (imperfect) channel state information (CSI) at the base station. The ... -
Dynamic Cloud Resources Allocation on Multidomain/Multiphysics Problems
(2015)The solution of multidomain/multiphysics problems is a computationally and memory demanding process, especially for large-scale differential equations. In this paper, we propose a cloud application that provides users a ... -
Dynamic cooperation enforcement through trust-based allocation policies in P2P systems
(2008)In this paper we propose distributed trust-based resource allocation policies to provide fairness in p2p-like systems. According to these policies, the portion of the available resource received by each competing peer ... -
Energy efficient resource allocation scheme via auction-based offloading in next-generation heterogeneous networks
(2017)The focus of this chapter is centered on the network underutilization during low traffic periods (e.g., night zone), which enables the Mobile Network Operators (MNOs) to save energy by having their traffic served by ... -
Green video delivery in LTE-based heterogeneous cellular networks
(2015)In this paper we present an optimization framework that formalizes the inherent trade-off between the user perceived quality of wireless video, and the energy consumption cost of the network. The former is formulated in ... -
An integrated multicriteria analysis tool for evaluating water resource management strategies
(2018)Water is involved, directly or indirectly, with many activities and needs that have to be met. The large scale and importance of water projects, the investments needed, the difficulty in predicting the results, and the ... -
An intelligent, uncertainty driven management scheme for software updates in pervasive IoT applications
(2018)The era of the Internet of Things (IoT) involves a huge number of autonomous devices (nodes) capable of monitoring and interacting with their environment. The autonomous devices are also able of being interconnected, thus, ... -
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 ... -
A market-based protocol with leasing support for globally distributed computing
(2001)We have developed JaWS, a Java-based Web computing system, which enables users to effortlessly export their machines in a global market of processing capacity to host remote computations (S. Lalis and A. Karipidis, 2000). ... -
Multi-RAT spectrum reallocation including carrier aggregation for 5G networks
(2018)Towards the 5G vision of massive access exploding the growth in data traffic, spectrum refarming and reallocation are considered key enabling technologies. Using spectrum reallocation (SR) with the spectrum originally ... -
On the Implementation of Matching Theory Based Resource Allocation in Networking Testbeds
(2020)In this paper, we demonstrate the implementation of a matching theory based algorithm that extends the well known Top-Trading-Cycles (TTC) in the resource allocation mechanism of the NITOS networking testbed. We first ... -
Online Algorithms for the Interval Scheduling Problem in the Cloud: Affinity Pair Threshold Based Approaches
(2022)In the interval scheduling problem, jobs have known start and end times (referred to as job intervals) and must be assigned to processing nodes for their whole duration. Although the problem originally stems from the ... -
