Self-adaptive Publish/Subscribe Network Design

The pub/sub pattern is gaining momentum in IoT architectures, thanks to its robustness and since it offers many-to-many communication. Efficient network management is needed when only scarce and unreliable resources are available as network infrastructure. Moreover, any form of centralized control should be avoided so as not to limit the application potential. This short paper presents preliminary results of a research line casting pub/sub communication as a dynamic network design problem and supporting optimized adaptive routing via a fully distributed Lagrangian matheuristic applied to an extension of the integer multicommodity flow problem.
