Abstract:
Real-time data collection in a hostile environment requires dealing with malicious failures in the sensing devices and the transport network:~such as data corruptions and message timeliness violations. Functional replication is employed to deal with failures, with voting among the replica devices to deliver a correct data to the end-user. Our goal is to develop a voting system that dynamically adapts its internal mechanisms to deal with various types of failures. The paper presents the design issues with considerations of protocol correctness, while achieving low message overhead and delivery latency under various failure scenarios. A case study of replicated web services is also presented.
