Past editions of M4IoT

Accepted Papers

Paper presentations are scheduled to December 6, 2021 at 09:00 Eastern Time (ET/GMT-5) and will be held virtually at the Zoom platform, with access restricted to participants registered in Middleware 2021. For other time zones, see timeanddate.com.


The Internet of Things (IoT) is creating new services and applications across various domains, including smart electricity grids, intelligent transportation, healthcare, smart homes, and energy management. As a consequence, a complex ecosystem of interconnected applications, services, and physical/virtual devices, with a high degree of heterogeneity, emerges. Such heterogeneity can be addressed by middleware platforms to abstract away the specificities of these devices, promote interoperability among them, and leverage the development of services and applications. In this ecosystem, enabled by middleware, devices share contextual data or receive control commands; services consume, process, and/or provide data; and applications leverage services and devices to fulfill users’ needs.

Topics of Interest

The International Workshop on Middleware and Applications for the Internet of Things - M4IoT focuses on two fundamental components in such ecosystems, namely (i) the middleware to compose applications, services, and devices and (ii) the applications built atop such middleware. Central topics of interest include the design, implementation, and operation of these components and how they process data and communicate with each other. Specific topics of interest include, but are not limited to:

Paper Submission and Publication

M4IoT 2021 seeks two kinds of paper submissions:

All submissions must be in Adobe Portable Document Format (PDF) and must comply with the ACM 2-column conference format (ACM_SigConf) available at this link. LaTeX users must use the acmart.cls class provided in the template with the conference format enabled at the document preamble:

Authors must use the ACM-Reference-Format.bst bibliography style also provided in the template:
The page limit includes all figures, tables, and references. Papers must be electronically submitted through the HotCRP system.

All submitted papers should describe original work and not be published or under review anywhere. The papers will be judged on the basis of their clarity, relevance, originality, and contribution. At least one author of each accepted paper must register at Middleware 2021 and present the paper during the workshop, otherwise the paper will not be included in the proceedings. Proceedings of previous editions of the M4IoT workshop are available here.

Important: Due to the COVID-19 situation, Middleware 2021 and M4IoT 2021 will be held virtually. Nonetheless, all accepted papers will be published at the ACM Digital Library.

Important Dates

Paper submission deadline: September 2, 2021 September 9, 2021 (AoE, GMT-12)
Author notification: September 27, 2021
