Abstract: The content based publish/subscribe paradigm has received emerging attention due to providing efficient loosely communication channels for large-scale distributed systems. Event publishing nodes don't specify the destination addresses of events;in contrast,events arc progressively routed to the nodes which have subscribed them However,existing content based event routing algorithms can't efficiently adapt to the dynamics of subscriptions and incur higher network communication costs. A content based adaptive event routing algorithm (CAER) was proposed. The subscription was bound with the corresponding subscribers' addresses in the routing tables, and then the routing tables were efficiently constructed and maintained. Simulation results show that the accuracy of the event publishing is improved, and the network communication costs arc significantly reduced.
