In recent years, the amount of information on the Internet has increased exponentially developing great interest in selective information dissemination systems. The publish/subscribe paradigm is particularly suited for designing systems for routing information and requests according to their content throughout wide-area network of brokers. Current publish/subscribe systems use limited syntax-ba...

In this proposal, we introduce a scalable distributed publish/subscribe system for selective information dissemination. We propose two models A-ToPSS and G-ToPSS for two different matching problems: approximate matching and semantic matching. A-ToPSS aims at processing uncertainty information, while G-ToPSS aims at filtering graph-based metadata. We describe problems left in these two models an...

Recently we have witnessed an increasing demand of fault-tolerant communications in publish/subscribe middleware. Although several reliable solutions have been proposed, none of them address the problem of achieving a resilient and timely event dissemination. We investigate how guaranteeing assured message dissemination despite occurrence of network faults without breaking temporal constraints....
