We describe a novel approach for content-based publish/subscribe system in mobile ad-hoc networks and show preliminary experiment results. We extended ODMRP (OnDemand Multicast Routing Protocol) using aggregated summaries of content-based subscriptions in Bloom filters expression for the dynamic construction of an event dissemination structure. ODMRP's mesh topology gives extra reliability. We describe experiment results including comparison with regular ODMRP and mobility simulation.
