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 ... -
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 ... -
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 ... -
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 ... -
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 ...
