Event broker grids, that deploy the publish/subscribe communication paradigm, extend the capabilities of seamless messaging in heterogeneous network environments. In order to support such mixed network environments, we integrate publish/subscribe semantics with multicast routing in mobile ad hoc networks. Dynamic construction of an event dissemination structure to route events from event publishers to subscribers is especially important to support highly dynamic, self-organizing, mobile peer-to-peer systems. The proposed approach aggregates content-based subscriptions in a compact data format (Bloom filters), and ODMRP (on-demand multicast routing protocol) is extended to use this context from the middleware-tier to construct an optimized dynamic dissemination mesh. Thus, dynamic multicast groups are created by aggregating subscriptions, applying K-means clustering and other methods. Cooperation between the middleware-tier and network components allows fine-grained subscriptions to be represented.
