Failure, connectivity and disconnection detectors
Lynda Temal, Denis Conan · 2004
In mobile environments, mobile terminals are subject to disconnections, for instance, when moving out of the range of a base station. In addition, users execute distributed applications that fail when a single crash occurs. These two extra-functionalities (disconnection management and fault tolerance) are supported by detection mechanisms (of connectivity and disconnection, and of failure). In this paper, we define the concepts of connectivity detector and disconnection detector, by comparison with unreliable failure detectors. These three types of detectors are then mixed for extending disconnection management and leveraging fault tolerance.
