Content Based Publish Subscribe is a communication and interaction paradigm that is quite promising to build complex software architectures. In particular its distributed incarnation can be used to decouple application components in dynamic environments, e.g. in peer to peer applications or in wireless mobile settings. However the dynamism characterizing these systems poses challenges in designing efficient routing structures. In this talk I will survey some popular approaches used for content based routing, from trees, to graphs, to structures more fit to mobile settings. In this journey I will focus on the work I have done at DEEPSE group at Politecnico di Milano: the REDS publish subscribe system, developed especially to address dynamic scenarios and a recent work on content based routing for sensor networks published this year at EWSN .


Matteo Migliavacca is a Research Associate at DSE group working on the SmartFlow project. He obtained a Ph.D. degree at Politecnico di Milano with a thesis on Middleware Services for Large Scale Dynamic Distributed Systems. His main research interests are in the Distributed Systems area, especially in routing, adaptivity, context-awareness and programming abstractions.
