Abstract:
Deep space communication occurs between devices on or orbiting different celestial bodies (e.g., different planets of the Solar System). Such environments are characterized by long delays (e.g., in the order of minutes or hours), intermittent communication opportunities, and relatively constrained resources (e.g., bandwidth, energy, etc.). More than two decades ago, the Internet Protocol (IP) stack was considered unsuitable for deep space communication, which led to the design of the Delay-Tolerant Networking (DTN) architecture and the Bundle Protocol (BP). However, recent work has revisited such an assessment, and the new IETF Taking IP to Other Planets (TIPTOP) working group has started to develop solutions to use an IP protocol architecture for deep space communication. This talk will present the motivation, current state of development, and issues of IP-based communication for deep space. The talk will also highlight the similarities between deep space and some Internet of Things (IoT) environments, and related opportunities.
Bio:
Prof. Carles Gomez received his Ph.D. degree from the Universitat Politècnica de Catalunya (UPC) in 2007. He is a Full Professor at the same university. He has worked in several publicly and privately funded research projects, and is (co)author of numerous technical contributions published in journals, conferences, books and IETF standards. His research interests focus primarily on wireless networks and the Internet of Things. Since 2019, he has been a chair of the IETF 6Lo working group. He has also served as editorial board member and guest editor of several scientific journals. He has been twice a visiting scholar at the Computer Laboratory of the University of Cambridge, under the supervision of Prof. Jon Crowcroft, in 2016 and in 2019, for one cumulative year. Since 2020, he has been included every year in the Stanford University’s list of the World's top 2% of scientists.
