A top-down approach for building realistic reference scenarios and simulation framework for LTE C-V2X communications
( Elsevier , 2023 , Article)Many vehicle-to-everything (V2X) applications and use cases require their feasibility to be simulated, tested, and validated in realistic traffic scenarios and under various network conditions before real-time testbed ... -
Automatic meter reading in the smart grid using contention based random access over the free cellular spectrum
( Elsevier , 2014 , Article)Real-time transmission of smart meter measurement data is investigated. A contention based approach exploiting the unused cellular spectrum, e.g. of 4G Long Term Evolution (LTE), is proposed. The proposed approach uses ... -
COVID-19 pandemic impacts on traffic system delay, fuel consumption and emissions
( Elsevier , 2021 , Article)A dramatic reduction in traffic demand has been observed during the COVID-19 pandemic, producing noticeable declines in traffic delays, energy consumption, and emissions. This unprecedented event provides us with the chance ... -
Delay-sensitive content distribution via peer-to-peer collaboration in public safety vehicular ad-hoc networks
( Elsevier , 2014 , Article)Delay-sensitive content distribution with peer-to-peer (P2P) cooperation in public safety vehicular networks is investigated. Two cooperative schemes are presented and analyzed. The first scheme is based on unicasting from ... -
Infrastructure-assisted joint power adaptation and routing for heterogeneous vehicular networks
( Elsevier , 2019 , Article)In vehicular networks, protocols and algorithms rely on the in-network status information and its delivery via control messages for their operations. Using the same wireless channel for data and control message transmissions ... -
Investigation on cellular LTE C-V2X network serving vehicular data traffic in realistic urban scenarios
( Elsevier , 2024 , Article)The need for reliable vehicular communication is an essential precondition of future Cooperative Intelligent Transportation Systems (C-ITS). The C-ITS applications and their diverse requirements necessitate a hybrid approach ... -
Joint energy-distortion aware algorithms for cooperative video streaming over LTE networks
( Elsevier , 2013 , Article)Real-time video streaming over long-term evolution (LTE) networks is investigated in the presence of mobile-to-mobile collaboration. A multi-objective problem for energy and distortion minimization is formulated and an ... -
Large-scale simulations and performance evaluation of connected cars - A V2V communication perspective
( Elsevier , 2017 , Article)Performance evaluation is integral to the vast majority of research on Vehicle-to-Vehicle (V2V) technology enabled connected cars. To validate ideas and concepts, researchers have been continuously striving towards the ... -
Mobile relays for enhanced broadband connectivity in high speed train systems
( Elsevier , 2014 , Article)With the introduction of wireless modems and smart phones, the passenger transport industry is witnessing a high demand to ensure not only the safety of the trains, but also to provide users with Internet access all the ... -
Real-time AI-based inference of people gender and age in highly crowded environments
( Elsevier , 2023 , Article)Gender identity is one of the most fundamental aspects of life. Automatic gender identification is increasingly being used in areas such as security, marketing, and social robots. The objective of this paper is to address ... -
Spatial opportunistic transmission for Quality of Experience satisfaction
( Elsevier , 2014 , Article)The capability of Multiple Input Multiple Output (MIMO) to deliver service simultaneously to more than one user is an exceptional characteristic for the cognitive radio (CR) communication. In this paper, statistical ...
