DynPubSub

Abstract

There are more and more IoT devices that produce and consume and ever increasing amount of data. Publish-subscribe (Pub/Sub) is a well known paradigm that simplifies the task of exchanging messages, as it decouples the communication between the entities that emit and consume messages. While traditionally deployed in a centralized cloud-based manner, the different components of a pub/sub system can be deployed directly onto the edge devices, in a peer-to-peer manner, to achieve the required low latency for most IoT applications. In this poster, we propose DynPubSub, a new peer-to-peer network overlay for topic based pub/sub systems deployed at the edge. DynPubSub provides fault tolerance and scalability, and aims at minimizing the latency while respecting the constraints of the edge devices and networks.
