Economics of mobile data offloading
(2013)Mobile data offloading is a promising approach to alleviate network congestion and enhance quality of service (QoS) in mobile cellular networks. In this paper, we investigate the economics of mobile data offloading through ... -
End-to-end bandwidth guarantees through fair local spectrum share in wireless ad-hoc networks
(2005)Sharing the common spectrum among the links in a vicinity is a fundamental problem in wireless ad-hoc networks. Lately, some scheduling approaches have been proposed that guarantee fair share of bandwidth among the links. ... -
Enhancing QoS Through Fluid Antenna Systems over Correlated Nakagami-m Fading Channels
(2022)Fluid antenna systems (FAS) enable mechanically flexible antennas that offer adaptability and flexibility for modern communication devices. In this work, we present a conceptual model for a single-antenna N-port (SANP) FAS ... -
Estimating downlink throughput from end-user measurements in mobile broadband networks
(2019)In recent years, Downlink (DL)throughput estimation in Mobile Broadband (MBB)networks has gained immense popularity and it is expected to become a vital component of the upcoming fifth generation (5G)systems. Plentiful ... -
Examining travelers "optimal strategies" in transit trip choices, applying a classification tree approach on transit quality of service indicators
(2014)According to Spiess and Florian (1989) [1], at each transfer point passengers may shape the "optimal" for them strategy taking into account minimum generalized travel cost. The generalized cost of trip choices is formulated ... -
Feasibility study of a HSPA backhauling over satellite for crisis management
(2011)The present paper studies the performance of a high-speed third-generation (3.5G) networking technology, HSPA (High Speed Packet Access), for delivering crisis management and emergency e-health applications under urgent ... -
First demonstration of service-differentiated converged optical sub-wavelength and LTE/WiFi networks over GEANT
(2015)A converged optical-wireless testbed is formed integrating TSON sub-wavelength networking in UK and the NITOS wireless solution in Greece. End-to-end service provisioning and flow differentiation are demonstrated across ... -
Gender Impact on Transit Quality of Service Importance and Performance Assessment
(2021)This paper examines the impact of gender on transit travelers’ quality assessment considering 26 indicators’ importance and performance ratings. Through an online survey and using a 5 point Likert scale, transit travelers ... -
Guidance Provision for Increasing Quality of Service of Public Transport
(2017)Travellers formulate their optimal strategyto follow for their trip, every time they may shift to another mode. Trip generalized cost is perceived based on quality of service aspects and type of traveller. One of the most ... -
An intelligent scheme for the identification of QoS violations in virtualized environments
(2018)Current networking applications involve the definition and utilization of multiple virtualized resources on top of the available infrastructure. Software defined networks increase the performance compared with legacy systems ... -
Investigating 5G V2X QoS using turbo codes
(2021)3rd Generation Partnership Project (3GPP) 5th Generation (5G) Vehicle-to-Everything (V2X) implementation scenarios represent typical applications of the new forthcoming technology. Quality of service (QoS) in 5G V2X services ... -
Investigation of Minibus Public Transport Service Characteristics in an Urban Area Through the Use of a Stated and Revealed Preference Survey
(2021)The operation of minibuses as public transport modes worldwide is considered as a both efficient and effective way to meet the mobility needs of special population groups in urban areas. Minibus services are more flexible ... -
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 multiuser downlink beamforming and admission control: A semidefinite relaxation approach
(2007)Multiuser downlink beamforming under quality of service (QoS) constraints has attracted considerable interest in recent years, because it is particularly appealing from a network operator's perspective (e.g., UMTS, 802.16e). ... -
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 ... -
Large scale “speedtest” experimentation in Mobile Broadband Networks
(2021)Characterizing and evaluating the performance of Mobile Broadband (MBB) networks is a vital need for today's societies. Testbed-based measurements are of great significance in this context, since they allow for controlled ... -
