16. Self-Organization in Peer-to-Peer Systems

Towards the definition of an information quality metric for information fusion models

“…In this research, we propose an IQ metric that supports an Information Fusion (IF) model based on a flat Peer-to-Peer (P2P) network (the connections among peers are formed arbitrarily and without any kind of hierarchy, that is, all the peers act as equals [1]) with no dedicated elements beforehand (servers, switches, hubs, and so on) [2]. The IF model works in a way that a certain external agent (denoted Ω) queries the P2P network, composed of different agents, in search for a certain information and then, the agents (denoted α) in the network collaborate for providing an answer as accurate as possible.…”

Overview and Challenges of Overlay Networks: A Survey

“…An open question is how much can self-organization emerge as an essential feature for improving the quality of the services. Requirements for selforganization in peer-to-peer networks [4] include issues like feedback, reduction of complexity, randomness, self-organized criticality and emergence.…”

Management of peer-to-peer overlays

“…Many existing P2P systems including DHT designs are relatively static to be considered self-organising in their model. de Meer and Koppen (2005) also evaluate several existing unstructured and structured overlays and determine that these satisfy few criteria for self-organisation.…”

“…Consequently conventional techniques for managing telecommunications networks (Terplan, 2001;Buford, 2001) and enterprise networks (Stallings, 1999) have not generally been applied to peer-to-peer overlays. Current mechanisms for self-organisation are limited (de Meer and Koppen, 2005;Biskupski et al, 2007) including inability to prevent free riders, adapt to imbalanced loads, and lack of metrics for detecting perturbations. Hence, as we discuss, active overlay management is needed to make overlays a sustainable platform for general purpose service delivery.…”
