Ubiquitous Systems and Its Applications

Dear Colleagues,

Today, we can find a myriad of devices, from the smallest to the biggest, from tiny sensors to large cloud data-centers, and examples such as smartwatches, smartphones, tablets, laptops, desktops, etc., all connected, continuously or intermittently, making a truly ubiquitous system. Thus, a ubiquitous system means that we have a very large number and different types of devices, all connected, thus providing an infrastructure for applications to run. Smart cities are just one of the use cases in which such a ubiquitous system is required. Many others exist already and will continue to appear and improve in the future, in several areas, such as home automation, health monitoring, driving assistance, gaming, etc.

This Special Issue entitled "Ubiquitous Systems and its Applications" focuses on distributed systems as the core technology to support ubiquity, as well as the corresponding applications running on top. Clearly, there are many challenges to overcome from which we are mostly interested on non-functional, e.g., scalability, availability, reliability, performance, security, etc.

Thus, the main purpose of this Special Issue is to provide both academic and industry researchers with a forum to present their research on the design, implementation and evaluation of ubiquitous systems and applications, not only for smart cities, but also for any scenario in which there is a similar need. Thus, we are also interested on identifying new application areas within this developing field. We encourage original research papers related to this topic, as well as high-quality review articles describing the current state-of-the-art.

In this Special Issue we are interested in contributions regarding the design, architecture, implementation and evaluation of both ubiquitous systems and ubiquitous applications. The technical areas include, but are not limited to:

• Mobile, parallel and distributed computing support for big data collection, processing and storage in ubiquitous systems
• Architecture, availability, and reliability of ubiquitous systems
• Security and privacy of ubiquitous systems
• Social computing, sensing and IoT for ubiquitous systems
• Application and experimental experiences of ubiquitous computing
• Design and implementation of web-based applications and apps in ubiquitous settings
• Ubiquitous vehicle-to-infrastructure integration
• Ubiquitous networks of sensors and actuators
• Open data and big data analytics in ubiquitous systems
• Internet of things (IoT) applications in ubiquitous systems
• Networks and communications for ubiquitous system
• Context information for ubiquitous systems
• Virtual machines for ubiquitous devices

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Sensor and Actuator Networks is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
