In this paper, we analyze the role of the social group in a Ubiquitous Computing (Ubicomp) environment as a source of contextual information. A model is presented to address the s...
We present a specification for a new, localized group membership service that maintains the membership status of adjacent nodes – called neighbors – in a mobile distributed s...
Group communications systems have been designed to provide an infrastructure for fault-tolerance in distributed systems, including wide-area systems. In our work on master-worker ...
Designing a distributed fault tolerance algorithm requires careful analysis of both fault models and diagnosis strategies. A system will fail if there are too many active faults, ...
Abstract. We describe a group membership protocol, called the timewheel group membership protocol, for a timed asynchronous distributed system. This protocol is a part of the timew...
