Distributed Multicast Grouping for Publish/Subscribe Over Mobile Ad Hoc Networks
Source: University of Cambridge
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, the authors 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 important, especially 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.
