Reliable Publish/Subscribe in Dynamic Ubiquitous Systems

摘要

This work addresses content-based publish/subscribe in dynamic ubiquitous scenarios, composed of a variety of heterogeneous devices connected by wireless networks, mobility being an intrinsic characteristic of this kind of systems. We present an approach based on the simple routing strategy, which is incrementally extended in order to support client and broker mobility. We allow both client and broker migration without the need to flood the network to notify of this change.
