DESCRIPTION:Estimados alumnos\n\n \n\nTenemos el agrado de invitarles a l
 a charla:\n\n“Direct-to-Satellite IoT and CubeSats: Efficient connectivi
 ty for resource-constrained devices”\n\nLa actividad estará a cargo de 
 Raydel Ortigueira\, Investigador PostDoctoral del Centro de Investigación
  Tecnológica en Sistemas Ciberfísicos (CPS-RTC).\n\n📅 Viernes 2 de oc
 tubre\n🕧 12:20 h\n📍 Sala de clases del DIE\n\n🥪 Habrá colación 
 para los asistentes.\n\nBiographical sketch: Raydel Ortigueira received th
 e B.S. degree in telecommunications and electronic engineering from the Hi
 gher Polytechnic Institute “José Antonio Echeverría\,” currently the
  Technological University of Havana (CUJAE)\, Havana\, Cuba\, in 2013\, an
 d the Ph.D. degree in electrical engineering from the University of Chile\
 , Santiago\, Chile\, in 2023. From 2013 to 2018\, he was an Instructor Pro
 fessor with the Department ofTelecommunications and Telematics\, CUJAE. Fr
 om 2024 to 2026\, Dr. Ortigueira was a postdoctoral researcher with the Ad
 vanced Center of Electrical and Electronic Engineering. (AC3E)\, Universid
 ad Técnica Federico Santa María\, Valparaíso\, Chile. Currently\, he is
  a postdoctoral researcher with the Cyber-Physical Systems Research and Te
 chnology Center (CPS-RTC). His research interests include medium-access co
 ntrol protocols\, time synchronization\, and resource allocation for direc
 t-to-satellite IoT networks.\n\n"Direct-to-Satellite IoT and CubeSats: Eff
 icient connectivity for resource-constrained device"\n\nAbstract: The Inte
 rnet of Things (IoT) enables data exchange from/to constrained devices suc
 h as sensors and actuators. When these devices are in remote areas without
  terrestrial network coverage\, direct-to-satellite IoT (DtS-IoT) systems 
 supported by CubeSat nanosatellites offer a cost-effective access network 
 solution. However\, this network\, composed of terrestrial IoT devices and
  CubeSats\, is characterized by energy\, processing\, and hardware constra
 ints that limit its performance\, as well as an increasing number of terre
 strial devices. Therefore\, communication protocols designed specifically 
 for these networks are necessary. In this talk\, Raydel will present an ap
 proach to address this issue: a scalable and energy-efficient medium acces
 s control (MAC) protocol that depends exclusively on the sensor nodes and 
 the CubeSat. Likewise\, he will present a satellite visibility prediction 
 algorithm for low-cost DtS-IoT systems\, which can operate in remote termi
 nals without Internet connectivity.\n\n \n\nhttps://indico.ing.puc.cl/eve
