Efficient dissemination in decentralized social networks

Abstract: Abstract-Online social networks (OSN) have attracted millions of users. This enormous success is not without problems; the centralized architectures of OSNs, storing the users' personal data, provides ample opportunity to privacy violation. These problems have raised the demand for open, decentralized alternatives. We tackle the research question: is it possible to build a decentralized OSN over a social overlay, i.e., an overlay network whose links among nodes mirror the social network relationships among the… Show more

“…The need and opportunities to implement P2P social networks is well documented [5,21], and has triggered a number of research efforts in this direction [6,8,9,11,16]. From the open source community, Diaspora 2 is the most notable example.…”

“…Recent proposals rely on gossiping protocols to build and maintain an overlay network whose links mirror the real social relations [9,16]. These systems are similar to ours, but do not trim the links to reduce the average and maximum node degrees.…”

“…We chose ego networks because i) they allow us to focus on relatively smaller networks, for which simulations are nonetheless already expensive, and ii) dissemination over ego networks is often a building block in SO-based approaches, including our own [13].…”

“…In [8] this is realized as a form of publish-subscribe over the social overlay. Instead, the work in [13] proposes an architecture for decentralized online social networks where the dissemination of information (e.g., profile updates) from a user to its corresponding ego network (i.e., the portion of the SO including the user, her friends, and the social links among them) is realized solely atop the social overlay.…”
