A Practical Distributed Universal Construction with Unknown Participants [PDF]
International Conference on Principles of Distributed Systems, 2014 Modern distributed systems employ atomic read-modify-write primitives to coordinate concurrent operations. Such primitives are typically built on top of a central server, or rely on an agreement protocol. Both approaches provide a universal construction,

Knowledge Connectivity Requirements for Solving Byzantine Consensus with Unknown Participants [PDF]
IEEE Transactions on Dependable and Secure Computing, 2018 Consensus is a fundamental building block to solve many practical problems that appear on reliable distributed systems. In spite of the fact that consensus is being widely studied in the context of standard networks, few studies have been conducted in order to solve it in dynamic and self-organizing systems characterized by unknown networks. While in a

Byzantine Agreement with Unknown Participants and Failures [PDF]
2021 IEEE International Parallel and Distributed Processing Symposium (IPDPS), 2021 A set of mutually distrusting participants that want to agree on a common opinion must solve an instance of a Byzantine agreement problem. These problems have been extensively studied in the literature. However, most of the existing solutions assume that the participants are aware of $n$ -- the total number of participants in the system -- and $f ...

Multi-resource Allocation with Unknown Participants [PDF]
2011 Second International Conference on Networking and Computing, 2011 We define the problem of multi-resource allocation, which is an extension of the dining philosophers problem. We apply this problem to systems where participants (here called clients) are unknown. We propose a solution for 2-resource allocation in static networks, then, explain how to modify our protocol to handle client dynamicity. Extend our solution

Byzantine Consensus with Unknown Participants [PDF]
International Conference on Principles of Distributed Systems, 2008 Consensus is a fundamental building block used to solve many practical problems that appear on reliable distributed systems. In spite of the fact that consensus is being widely studied in the context of classical networks, few studies have been conducted in order to solve it in the context of dynamic and self-organizing systems characterized by unknown

Consensus with Unknown Participants or Fundamental Self-Organization [PDF]
International Conference on Ad-Hoc, Mobile and Wireless Networks, 2004 We consider the problem of bootstrapping self-organized mobile ad hoc networks (MANET), i.e. reliably determining in a distributed and self-organized manner the services to be offered by each node when neither the identity nor the number of the nodes in the network is initially available.

Sheroes: Feasibility and Acceptability of a Community-Driven, Group-Level HIV Intervention Program for Transgender Women. [PDF]
, 2020 Transgender women experience disproportionate risk of HIV acquisition and transmission. We piloted 'Sheroes', a peer-led group-level intervention for transgender women of any HIV status emphasizing empowerment and gender affirmation to reduce HIV risk ...
