23^rd ACM MSWiM 2020

The technical program of the 23rd ACM International Conference on Modeling, Analysis, and Simulation of Wireless and Mobile Systems (MSWiM), exceptionally held virtually in November 2020, highlights the high standard of past editions of the conference. In 2020, the call for papers attracted the relevant number of 100 submissions for review in all areas of mobile and wireless systems. The submitted papers came from all over the world, for a total of 32 countries, reflecting the worldwide visibility and the international profile of MSWiM.

Most addressed topics of MSWiM'20 were Wireless Communication and Networks, Network Simulations and Simulators, Performance Evaluation, and Ad Hoc Networks. These topics confirm that the focus of the conference is on modeling and analyzing wireless networks, also based on simulated environments. Other addressed topics such as Vehicular Networks, Edge/Fog Computing, and IoT & Energy demonstrate the relevance of modeling and simulating wireless environments in research fields emerged and affirmed more recently. Such considerations confirm the prominent importance of MSWiM as an international reference point for the research community actively investigating paramount topics ranging from modeling of mobile and wireless systems to their simulation and measurements, also when applied in specific environments such as vehicular networking and Internet of Things.

The submissions included a large number of papers of very high quality, making the selection process difficult and competitive. The members of the Technical Program Committee worked efficiently and responsibly under tight time constraints to produce the reviews (at least 3 independent reviews for any paper) for the final paper selection. In the end, after this rigorous review process, we were able to select 24 regular papers, which correspond to an acceptance rate of 24%. An additional small set of 6 short papers were recommended to be included in the technical program owing to their quality and contribution.

Among the full regular papers, the following four were shortlisted as candidates for the best paper award:

• Platooning on the edge. by Christian Quadri (Universita degli Studi di Milano, Italy); Vincenzo Mancuso (IMDEA Networks Institute, Spain); Marco Ajmone Marsan (Politecnico di Torino, Italy); Gian Paolo Rossi (Universita degli Studi di Milano)
• A Mixture Density Channel Model for Deep Learning-Based Wireless Physical Layer Design by Dolores García Martí (IMDEA Networks Institute, Spain, University Carlos III, Spain); Joan Palacios Beltran (IMDEA Networks Institute, Spain, University Carlos III, Spain); Jesus Omar Lacruz (IMDEA Networks Institute, Spain); Joerg Widmer (IMDEA Networks Institute, Spain)
• Revisiting Wi-Fi Performance under the Impact of Corrupted Channel State Information by Youngwook Son (Seoul National University, Korea); Saewoong Bahk (Seoul National University, Korea)

Based also on presentation quality and on the evaluation of a committee working during the MSWiM'20 conference, the winner among these three papers will be announced at the conference closing event and will be reported in the proceedings of the next edition of the conference (MSWiM'21).
At this point, we take the opportunity of this welcome message to congratulate the winners of the best Regular paper award for MSWiM'19:

• SEE: Scheduling Early Exit for Mobile DNN Inference during Service Outage by Zizhao Wang, Wei Bao and Dong Yuan (The University of Sydney, Australia); Liming Ge (University of Sydney, Australia); Nguyen H. Tran and Albert Zomaya (The University of Sydney, Australia)

and the winner for best Short paper award for MSWiM'19:

• COLiDeR: A Cross-Layer Protocol for Two-Path Relaying by Raphael Naves and Gentian Jakllari (University of Toulouse, France); Hicham Khalife and Vania Conan (Thales Communications & Security, France); Andre-Luc Beylot (University of Toulouse, France)

Moreover, MSWiM'20 will host two very interesting keynotes:

• Challenges Towards the Next Generation of Mobile Communications , Arturo Azcorra, Universidad Carlos III de Madrid, Spain
• Lightweight Short-term Photovoltaic Power Prediction for Edge Computing , Albert Y. Zomaya, University of Sydney, Australia

Finally, let us note that the excellent and very interesting technical program would not have been possible without the dedication of many colleagues. We would like to thank all the members of the Technical Program Committee; special thanks go to all the members of the Organizing Committee and, last but certainly not least, to the General Chair Monica Aguilar Igartua, the Vice General Chair Paolo Bellavista, and the Steering Committee. Thanks to their dedicated work, we are now able and happy to welcome you to this promising edition of the ACM MSWiM'20, with a vibrant technical program that will certainly attract your interest and stimulate fruitful discussions. Enjoy!
