Abstract: In the last few years, the number of IoT applications that rely on stream processing has increased significantly. These applications process continuous streams of data with a low delay and provide valuable information. To meet the stringent latency requirements and the need for real-time results that they require, the components of the stream processing pipeline can be deployed directly onto the edge layer to benefit from the resources and capabilities that the swarm of edge devices can provide. In this poster, we outline some ongoing research ideas into deploying stream processing operators onto edge nodes, with the goal of minimizing latency while ensuring that the constraints of the devices and their network capabilities are respected. More precisely, we provide a modeling of the semantics of the operators that considers the interactions between different operators, the parallelism of concurrent operators, as well as the latency and bandwidth usage.

DynPubSub: A Peer To Peer Overlay For Topic-Based Pub/Sub Systems Deployed at the Edge

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.

A preliminary study of open-source IoT development frameworks

Baba-Cheikh, Z., El-Boussaidi, G., Gascon-Samson, J., Mili, H. and Guéhéneuc, Y.G. (2020) A preliminary study of open-source IoT development frameworks. Proceedings of the IEEE/ACM 42nd International Conference on Software Engineering Workshops (ICSE Workshops) 2020

Abstract: The Internet of Things (IoT) market is growing fast with an increasing number of connected devices. This led many software companies to shift their focus to develop and provide IoT solutions. IoT development has its own challenges as typical IoT solutions are composed of heterogeneous devices, protocols and software. To cope with these challenges, many frameworks are available to help developers to build IoT applications. Some of these frameworks are open source and might be of great interest for small and medium-sized companies wishing to build IoT solutions at a lower cost. In this paper, we present the results of a preliminary study of four open source IoT development frameworks. In particular, we used these frameworks to implement a sample of three IoT applications and we analyze them against a minimal set of IoT requirements. We focus in our study on the IoT development for Raspberry PI as it is a very low-cost and popular platform.
