Avatar: A Time- and Space-Efficient Self-Stabilizing Overlay Network [article]

Andrew Berns
2015 arXiv   pre-print
Recently, self-stabilizing overlay networks have been presented as a method for managing this complexity.  ...  Self-stabilizing overlay networks promise that, starting from any weakly-connected configuration, a correct overlay network will eventually be built.  ...  Pemmaraju and Dr. Sukumar Ghosh, for their guidance and discussions on this paper.  ...

Network Scaffolding for Efficient Stabilization of the Chord Overlay Network [article]

Andrew Berns
2021 arXiv   pre-print
In this work, we address this issue by presenting an algorithm for building a Chord network that has polylogarithmic time and space complexity.  ...  From data centers to IoT devices, overlay networks are used to organize a diverse set of processes for efficient operations like searching and routing.  ...  To date, we are aware of only one self-stabilizing overlay network that is efficient in terms of both time and space.  ...

Dynamic Group Membership Management for Distributed Interactive Applications

Knut-Helge Vik, Carsten Griwodz, Pal Halvorsen
2007 32nd IEEE Conference on Local Computer Networks (LCN 2007)  
They are compared with respect to four metrics that can be relevant for a distributed interactive application. These are total tree cost, diameter, reconfiguration time and stability.  ...  The group membership changes over time, and the group division is unrelated to the physical proximity.  ...  To avoid these problems, we build overlay networks.  ...

A survey of peer-to-peer overlay approaches for networked virtual environments

Eliya Buyukkaya, Maha Abdallah, Gwendal Simon
2013 Peer-to-Peer Networking and Applications  
This paper identifies and analyzes the key design approaches that have been proposed over the last decade to construct a peer-to-peer (P2P) networked virtual environment (NVE) systems.  ...  We discuss each approach, their advantages and drawbacks, and examine several representative P2P-based NVE systems based on the presented approaches, thus providing the background and literature review  ...  Fully distributed architectures exhibit extra-ordinary self-healing and self-stabilizing properties.  ...

Combining Peer-to-Peer and Cloud Computing for Large Scale On-line Games [article]

Emanuele Carlini
2015 arXiv   pre-print
MMOGs are large-scale distributed applications where a large number of users concurrently share a real-time virtual environment.  ...  P2P- based solutions present several advantages, including the inherent scalability, self-repairing, and natural load distribution capabilities.  ...  In addition, DHT-based approaches often provide stabilization mechanisms that helps in self-repairing the overlay.  ...

Designing Benchmarks for P2P Systems [chapter]

Max Lehn, Tonio Triebel, Christian Gross, Dominik Stingl, Karsten Saller, Wolfgang Effelsberg, Alexandra Kovacevic, Ralf Steinmetz
2010 Lecture Notes in Computer Science  
In this paper we discuss requirements for peer-to-peer (P2P) benchmarking, and we present two exemplary approaches to benchmarks for Distributed Hashtables (DHT) and P2P gaming overlays.  ...  A set of common P2P quality metrics helps to achieve a comprehensive selection of workloads and metrics for each scenario.  ...  The result quality metrics are recall and precision; efficiency is measured as query response time and network resource consumption.  ...

2020 biorxiv/medrxiv   pre-print
Grid cells in entorhinal cortex (EC) encode an individual's location in space and rely on environmental cues and self-motion cues derived from the individual's body.  ...  Body-derived signals are also primary signals for the sense of self as located in space (i.e. bodily self-consciousness, BSC).  ...  Rayleigh's z-value was taken as an index of the spatial stability of the session 34, 35 . Temporal stability was defined as the stability of grid-orientations over time.  ...
