Polyzos Mobile Multimedia Laboratory Department of Informatics Athens University of Economics and Business Evelpidon 47A, Athens 11362, Greece {vsiris, polyzos}@aueb.gr Due to their inherent wide coverage, dependability and resilience properties, Satellite Communications (SatCom) can play an integral role within several Future Internet (FI) application domains that address Grand Societal Challenges towards a sustainable and efficient economy [1-3]. E.g., SatCom can effectively support smart FI- enabled transportation systems, smart FI-enabled security and public safety systems, as well as smart FI-enabled healthcare systems. Such FI application domains refer to information collection and dissemination services/applications within the “Internet of Things” communication paradigm, where the real physical world is connected to the digital world through a multitude of sensors and actuators. In particular, satellite M2M (Machine-to-Machine) communications, currently a relatively small market compared to that of terrestrial wireless networks, is expanding, led by the growing need to track and monitor difficult-to-reach valuable assets. Satellite M2M networking is gaining popularity in a wide range of governmental and commercial markets owing to the considerable benefits offered by the technology [4]. For specific industries, such as oil and gas, utilities, transportation and logistics, wherein large numbers of assets are deployed in remote locations with inadequate cellular coverage, M2M becomes an expensive proposition unless satellite networks are used (and deployed, if needed). Satellite M2M is preferred for high-end applications requiring wide coverage, particularly in oceans, deserted or rural areas, and for performing e.g., environmental monitoring, mission-critical monitoring, video surveillance etc. Figure 1: Satellite-assisted ICN-based FI Network Architecture The information collection and dissemination services/applications above are a perfect match for Information- Centric Networking (ICN) architectures (see e.g., [5-7]). ICN is built around information, rather than the end-points where it resides or is produced. This has a number of advantages that are explored and exploited by various proposed architectures in the context of the FI, such as the Publish-Subscribe Internet Routing Paradigm (PSIRP), Content Centric Networking (CCN), Named Data Networking (NDN), Network of Information (NetInf), Data- Oriented Network Architecture (DONA) and Cache-aNd-Forward (CNF). In our context it can be exploited in a more flexible and adaptive notion of “service.”, e.g., in a community‐based service where car drivers disseminate information about traffic jams and alternative routes by‐passing them. Thus, we can move from a server or host‐centric view of services provided typically by a single provider, to an information-centric view of services * This work is being done under the ESA ARTES 1 project “φSAT” (The Role of Satellite in Future Internet Services) – ESA/ESTEC Contract No.: 4000103360/11/NL/NR.
