Situational context for replica voting based data collection in hostile environments
Mohammad Rabby, Kaliappa Ravindran · 2011
The paper discusses the infusion of context awareness in the management of data quality in a replicated sensor based data collection network. Given a 2-phase voting protocol to decide on data delivery from sensors to the end-user, the paper discusses the impact of environment parameters (such as fault severity and network message loss) and resource parameters (such as network bandwidth and number of replicas) on the quality of user-level data delivery. The degree of control is determined by the contextual inputs that capture the dynamically changing scope and importance of data to the application.
