24th ACM MSWiM 2021 Program Chairs’ Welcome

The technical program of the 24th ACM International Conference on Modeling, Analysis, and Simulation of Wireless and Mobile Systems (MSWiM), successfully held virtually in November 2021, highlights the high standard of past editions of the conference. In 2021, the call for papers attracted 113 submissions for review in all areas of mobile and wireless systems. The submitted papers came from all over the world, for a total of 29 countries, reflecting the worldwide visibility and the international profile of MSWiM. Most addressed topics of MSWiM 2021 are Wireless Communication and Networks, Channel Access in Wireless Networks, and Network Simulation Experiments and Testbeds. These topics confirm that the focus of the conference is on modeling and analyzing wireless networks, based on simulated environments. Other addressed topics such as Vehicular and Aerial Networks, Edge/Fog Computing, and IoT demonstrate the relevance of modeling and simulating wireless environments in research fields emerging 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 22 regular papers, which correspond to an acceptance rate of 19.5%. An additional small set of 7 short papers were recommended to be included in the technical program owing to their quality and contribution.
