Ensuring Low-Latency and Scalable Data Dissemination for Smart-City Applications

Low latency and scalable data dissemination is a critical requirement for many IoT applications, e.g., smart city applications, which are often realized by using the publish/subscribe communication paradigm. Ensuring low latency requires effective load balancing of the publish/subscribe topics across the different publishers and subscribers. To that end we present ongoing work on a data-driven approach to learning a latency-aware model of IoT broker loads, and in turn using it to determine broker replication, and balancing topics across them.
