Content-based routing with on-demand multicast
Eiko Yoneki, Jean Bacon · 2004
We present a novel approach for messaging systems with content-based subscription in mobile ad-hoc networks. Dynamic construction of an event dissemination structure to route events from message producers to consumers is important to support rapidly changing multihop topologies over wireless links. The proposed approach uses summaries of content-based subscriptions to construct an event dissemination structure and Bloom filters are used to summarize subscriptions. We extend ODMRP (on-demand multicast routing protocol) to utilize this context from the middleware tier and construct an optimized dynamic dissemination mesh. ODMRP's mesh topology gives extra reliability compared to the tree structure in unstable mobile ad-hoc network environments.
