A survey of architectures and scenarios in satellite-based wireless sensor networks: system design aspects
Nedo Celandroni,Erina Ferro,Alberto Gotta,Gabriele Oligeri,Cesare Roseti,Michele Luglio,Igor Bisio,Marco Cello,Franco Davoli,Athanasios D. Panagopoulos,Marios I. Poulakis,Stavroula Vassaki,T. de Cola,M. A. Marchitti,Yim Fun Hu,Prashant Pillai,Suraj Verma,K. Xu,Guray Acar +18 more
TL;DR: Architectural aspects related to WSNs in some way connected with a satellite link are addressed, a topic that presents challenging interworking aspects and requirements of the most meaningful WSN applications have been drawn and matched to characteristics of various satellite/space systems.
Journal ArticleDOI
Asynchronous Contention Resolution Diversity ALOHA: Making CRDSA Truly Asynchronous
TL;DR: Asynchronous contention resolution diversity ALOHA (ACRDA) is described in detail, which represents the evolution of the CRDSA RA scheme and provides better throughput performance with reduced demodulator complexity and lower transmission latency than its predecessor while allowing truly asynchronous access to the shared medium.
Journal ArticleDOI
Multiple access in DVB‐RCS2 user uplinks
TL;DR: An analytical model for the DVB‐RCS2 RA load control algorithm is proposed followed by performance assessment via numerical computations and simulations.
Journal ArticleDOI
Towards the implementation of advanced random access schemes for satellite IoT
Marco Krondorf,Martin Goblirsch,Riccardo De Gaudenzi,Giuseppe Cocco,Giuseppe Cocco,Nikolaos Toptsidis,Guray Acar +6 more
TL;DR: This paper investigates the design and optimization of RA burst demodulator algorithms for single‐frequency and multifrequency CRDSA and ACRDA and evaluates the performance of such algorithms in a number of system scenarios of practical interest and studies the impact of relevant system parameters on several performance metrics.
Proceedings ArticleDOI
HydRON: internet backbone beyond the cloud(s)
Christopher Vasko,Josep Perdigues,Guray Acar,Pantelis-Daniel Arapoglou,Wael El-Dali,Silvia Mezzasoma,Monica Politano,Zoran Sodnik,Carlo Elia,Harald Hauschildt +9 more
TL;DR: HydRON-DS represents the initial stage serving the purpose to gradually demonstrate key technologies required to deploy a first (all) optical transport network at terabit-per-second capacity in space and the seamless extension of terrestrial fibre-based networks into space.
