Publish/Subscribe System

    Event-driven publish/subscribe (PS) systems are widely used in various types of applications. We consider a peer-to-peer (P2P) model of a topic-based PS system which is composed of peer processes (peers) with no centralized coordinator. My study, each peer publishes a message with publication topics while receiving messages whose publication topics are in the subscription topics of the peer. Each peer has to deliver every pair of event messages related with respect to topics in the causal order of publication events. We discuss topic-based causally (TBC) precedent relation among messages. Here, each peer delivers event messages which are related with respect to topics. I think that newly propose an implicitly causally precedent relation among messages in the TBC order. Which are related with respect to topics.
